<p><em>The PPCW railroad flatcars is railroad flatcars used to transport container loads with a maximum load capacity of up to 42 tons. In its use, these railroad flatcars are used to transport the cement bags in the pallet arrangement resulting in crack in the bottom frame of the PPCW railroad flatcars structure. The purpose of this analysis is to find out stress value and deformation value that occurred in the railroad flatcars due to the cement bags loading. The analysis process begins with modeling according to the original size of the railroad flatcars which is then followed by providing the support, gravity, loads, and material specifications used. Based on the result of analysis that has been obtained from the load of cement bags of 546,000 N and ratchet lashing of 900,000 N on the frame of PPCW railroad flatcars, we obtained the maximum von Mises stress value of 231.91 MPa arising on the bottom frame of the PPCW railroad flatcars structure as the site of cracking and the maximum total deformation value of 19.526 mm arising in the center of the railroad flatcars. The PPCW railroad flatcars made from SS400 with yield strength value of 245 MPa. Therefore, it was found that the value of stress arising in the railroad flatcars is still in the safe area and is allowed</em><em>.</em><em></em></p>

Objective: The objective of this study was to compare the biomechanical differences of different rod configurations following anterior column realignment (ACR) and pedicle subtraction osteotomy (PSO) for an optimal correction technique and rod configuration that would minimize the risk of rod failure.Methods: A validated spinopelvic (L1-pelvis) finite element model was used to simulate ACR at the L3–4 level. The ACR procedure was followed by dual-rod fixation, and for 4-rod constructs, either medial/lateral accessory rods (connected to primary rods) or satellite rods (directly connected to ACR level screws). The range of motion (ROM), maximum von Mises stress on the rods, and factor of safety (FOS) were calculated for the ACR models and compared to the existing literature of different PSO rod configurations.Results: All of the 4-rod ACR constructs showed a reduction in ROM and maximum von Mises stress compared to the dual-rod ACR construct. Additionally, all of the 4-rod ACR constructs showed greater percentage reduction in ROM and maximum von Mises stress compared to the PSO 4-rod configurations. The ACR satellite rod construct had the maximum stress reduction i.e., 47.3% compared to dual-rod construct and showed the highest FOS (4.76). These findings are consistent with existing literature that supports the use of satellite rods to reduce the occurrence of rod fracture.Conclusion: Our findings suggest that the ACR satellite rod construct may be the most beneficial in reducing the risk of rod failure compared to all other PSO and ACR constructs.

The primary link of an IC engine is a connecting rod. Its position is in-between the crankshaft and the piston whose key function is to convert the piston motion which is reciprocating in nature into rotary motion of the crank by transmitting the piston thrust to the crankshaft. This has entailed performing a detailed load analysis. In this paper, connecting rod's finite element analysis was done using Finite Element techniques. So firstly by using the schematic diagram the solid model of the connecting rod was created using Solid works software. Then using the Ansys R17.1 software the meshing was done and then the Finite element analysis is done to find the Equivalent (Von-Mises) stresses and the Factor of Safety under the loading conditions. Structural Steel is the material which is used for connecting rod and the loading conditions are assumed to be static. In Equivalent (Von-Mises) stress test maximum stress is found to be 1.504x108 Pa and the minimum factor of safety is 1.20765 for the connecting rod

A high stress condition in the hip system may cause fracture of the ball head. This failure may appear after a heavy accident such as sudden fall. The aim of this investigation is to make a computer simulated model of the hip system to evaluate the regions of stress concentration as well as the pressure in the stem-ball junction. 3D Non-Linear Finite Element Analyses were performed taking into consideration a high peak load to simulate trauma conditions. Ball heads from 22 to 36 mm in diameter were modeled, and also two sizes for taper lock were simulated to report their influence on the stresses over the critical areas of the ball head. Two different materials of common ball head ceramics (Alumina and Zirconia) were considered to evaluate its relation to the stresses produced. It was found that the ball head cone’s depth has major incidence in the stress concentration surrounding the stem when an impact load is applied, and that a deeper cone may offer a more relieved loading configuration when considering stress related parameters such as Von Mises stress, contact pressure and friction stress.

Standard procedures available for evaluating gear fillet stresses are targeted to circular gears where little information is available about noncircular gears. In this paper, a mesh generation algorithm is presented for the discretization of gear tooth profiles of noncircular gear elements for static stress evaluation using FEM (Finite Element Method). The procedure assumes that the noncircular gear tooth profile is known. Delimiting a tooth domain from the gear structure and subdividing it into sectors, the gear tooth mesh is generated by mapping pregenerated patterns into the sectors. The discretized tooth domain is used in conjunction with the FEM to obtain stresses within the tooth fillet region. For comparison, this procedure was applied to determine the stress distribution in circular gears and rectangular beams. The results were in complete agreement with existing analytical solutions. An illustrating example is presented where a noncircular gear pair is introduced to eliminate the speed and torque fluctuation that exists in an electrical generator when an I.C. engine is used as the power source for the generator. The maximum fillet Von Mises stress is calculated for each angular position of the noncircular gear pair.

Dragline teeth are used to dig overburden rocks and fill the bucket by its action in surface mining. Thus, these teeth are very important for a better performance of the dragline. In the present investigation, efforts were made to determine the failure zone within the teeth through modeling, using the finite element software ANSYS workbench. The maximum deformation and maximum von-Mises stress were 0.286 mm and 801.38 MPa, respectively. From fatigue analysis, the minimum tool life was 24 540 cycle and the minimum factor of safety was 0.1 at the tip of the tool. Beyond the cutting edge (tip), the factor of safety was greater than 1.13. Finite element analysis was extended by varying the working load on the edge of the tool (68–86 tonnes) as well as the cutting angle (30°–36°). It was found that if the working load was increased, both corresponding maximum deformation and maximum von-Mises stress were increased, while the factor of safety was decreased. In the scanning electron microscopy analysis, wear phenomena such as rock intermixed, fracture of WC-grain, oxidized WC-grain, plastic deformation, cavity formation, cracking, and crushing were visible at magnification of 1000×.

Helical compression spring plays a vital role in vehicle application as it improves ride index, sustains the vehicle against extreme degrees of vibration and stress induced on the suspension system as a result of uneven road. Depending on the extent of load acting on the suspension system, material selection, design considerations and manufacturing processes, longevity and performance of the spring may be sustained, otherwise the spring may fail prematurely under severe loading condition. In this study, compression spring was designed using high carbon steel, stainless steel and chrome vanadium steel and the designed spring models were simulated for maximum Von-mises stress, maximum resultant displacement and resultant strain. Curb weight of the vehicle was considered in the analysis which involves the weight of the car with all fluids and components but without the driver, passengers, and cargo. At the end of the simulation, the three materials remained within the limit of their elasticity without any significant sign of failure under the applied load of 3888N. However, the difference between Von-mises stress obtained for Chrome vanadium and its yield strength was the highest (653MPa) followed by stainless steel (235MPa) before high carbon steel (109MPa). This implies that at increasing loading conditions, high carbon steel will be the first material to fail during operation, whereas, stainless steel and chrome vanadium may exhibit sustained level of longevity before failure as a result of the high chromium content and other alloying elements that gives them a better quality but at relatively high cost compared to high carbon steel which can satisfactorily undergo its service condition at relatively low cost.

An ideal occlusal scheme plays an important role in a good prognosis of All-on-Four applications, as it does for other implant therapies, due to the potential impact of occlusal loads on implant prosthetic components. The aim of the present three-dimensional (3D) finite element analysis (FEA) study was to investigate the stresses on abutments, screws and prostheses that are generated by occlusal loads via different occlusal schemes in the All-on-Four concept. Three-dimensional models of the maxilla, mandible, implants, implant substructures and prostheses were designed according to the All-on-Four concept. Forces were applied from the occlusal contact points formed in maximum intercuspation and eccentric movements in canine guidance occlusion (CGO), group function occlusion (GFO) and lingualized occlusion (LO). The von Mises stress values for abutment and screws and deformation values for prostheses were obtained and results were evaluated comparatively. It was observed that the stresses on screws and abutments were more evenly distributed in GFO. Maximum deformation values for prosthesis were observed in the CFO model for lateral movement both in the maxilla and mandible. Within the limits of the present study, GFO may be suggested to reduce stresses on screws, abutments and prostheses in the All-on-Four concept.
