The wheel of a vehicle plays a vital role to bear the load applies on it. Generally spokes acts as the supports between the wheel rim and hub. These spokes must have sufficient strength and stiffness to avoid the failure of the wheel. In present days these wheels are made up of aluminum alloy, magnesium alloy and steel. To reduce the weight of the wheel many wheel designs are implemented and applied for different vehicles. In this paper three different wheel designs are chosen, those are inclined spokes, curved spokes and Y shaped spokes made up of Al alloy, Mg alloy and Steel. Static structural analysis subjected to pressure on the wheel rim and free vibrational analyses are performed by using finite element analysis tool Ansys 12. The objective of the present work is to observe the best design which contains higher structural stiffness, specific structural stiffness with lower von mises stresses under static load conditions. It is observed that curve shaped spoke designs are better in for manufacturing of wheel in both static and dynamic point of view.

The wheel rim plays a vital role for good running of the vehicle and the most important safety components from a structural point of view. It must be made with adequate strength and lighter in weight to reduce the unsprung mass of the vehicle and plays a major role in vehicle dynamics. The present study deals with the comparison of structural analysis of aluminium bronze alloy wheel rim with three different compositions to enhance corrosion and fatigue resistance. The design of the wheel rim was created by CATIA V5 and structural behaviour was analysed by ANSYS workbench. The results showed that combination of 90% Al alloy and 10% CuSn) gives adequate strength compared to other combinations of aluminium and bronze. The fabrication of the rim was done by casting methods. Various test like impact, shear, hardness and ultimate tensile tests were conducted to know the mechanical strength of the rim. Salt spray corrosion test was carried out to know the corrosion behaviour of the rim and the results show that no corrosion was found up-to 240 hours

Digital elevation model (DEM) plays a vital role in hydrological modelling and environmental studies. Many essential layers can be extracted from this land surface information, including slope, aspect, rivers, and curvature. Therefore, DEM quality and accuracy will affect the extracted features and the whole process of modeling. Despite freely available DEMs from various sources, many researchers generate this information for their areas from various observations. Sentinal-1 synthetic aperture radar (SAR) images are among the best Earth observations for DEM generation thanks to their availabilities, high-resolution, and C-band sensitivity to surface structure. This paper presents a comparative study, from a hydrological point of view, on the quality and reliability of the DEMs generated from Sentinel-1 data and DEMs from other sources such as AIRSAR, ALOS-PALSAR, TanDEM-X, and SRTM. To this end, pair of Sentinel-1 data were acquired and processed using the SAR interferometry technique to produce a DEM for two different study areas of a part of the Cameron Highlands, Pahang, Malaysia, a part of Sanandaj, Iran. Based on the estimated linear regression and standard errors, generating DEM from Sentinel-1 did not yield promising results. The river streams for all DEMs were extracted using geospatial analysis tool in a geographic information system (GIS) environment. The results indicated that because of the higher spatial resolution (compared to SRTM and TanDEM-X), more stream orders were delineated from AIRSAR and Sentinel-1 DEMs. Due to the shorter perpendicular baseline, the phase decorrelation in the created DEM resulted in a lot of noise. At the same time, results from ground control points (GCPs) showed that the created DEM from Sentinel-1 is not promising. Therefore, other DEMs’ performance, such as 90-meters’ TanDEM-X and 30-meters’ SRTM, are better than Sentinel-1 DEM (with a better spatial resolution).

AbstractFinite Element Modeling was used to compare the efficacy of common screw-plate configurations used for fixation of parasymphyseal fractures of the mandible. Measures of Von Mises stress on the screw bone interface, as well as principal strain in the reduced fracture region, were used in this comparison. This study also explored differences between orthotropic and isotropic modeling practices and compared the effect of mastication forces on both the fractured and intact halves of the mandible. The results of this analysis showed no major differences between configurations from a mechanistic point of view. This suggests that the use of any of the studied screw-plate configurations will not increase chances for post-operative complications. Furthermore, little difference is seen between analyses with either orthotropic or isotropic material properties. The inclusion of orthotropic properties can thus be avoided in future studies with similar boundary and plating conditions. Mastication ipsilateral to the fracture increases Von Mises stress 2 to 4 times, and should be avoided during early healing periods. These recommendations only apply to patients whose fractures mimic the finite-element model.

A steering upright is one of the vital components in vehicle dynamics which links all suspension components between the wheel and therefore the vehicle. Upright provides the linkage between the upper & lower ball joints. The upright connects components as an example, control arms, steering arms, suspension springs, shock absorber, brake disc, wheels & tire. Steering upright is a part of mechanical system which contains the wheel hub and assembles to the suspension components. It's the pivot point of the steering and mechanical system, which allows the front wheels to show & more. Agenda of this project is design optimization of steering upright to achieve weight reduction along with required strength and stiffness. Optimized design of upright is necessary with correct material selection further as valid finite element analysis. Optimization is accomplished considering static stress, strain and total deformation analysis with acceptable material selection. Modal and Fourier analysis is to be performed to see natural frequencies and deformation. The experimental testing is going to be performed on UTM. By making the comparative analysis, result and conclusion is drawn.

The success in the chewing process depends on the performance of the tooth used. Actually, taking care of the tooth and improving its performance can change our life. Therefore, the treatment process of the teeth has become more necessary in the life of a dental patient. Nowadays, a post plays an important vital role in this process. In the present work, analysis of the effect of the post material on the performances of the components of endodontically treated teeth (ETT) was carried out through the finite element analysis (FEA). The effects of post material on the von Mises stress component (Svon), shear stress, and displacement component (Usum) occurred on the all components of ETT were investigated. After that, the determination of the optimum material for an endodontic prefabricated post (EPP) was investigated through the sub-problem approximation method.

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.
