The Effects of Oblique Running and Ideal Motion on Stress Analysis of Bridge Crane Wheels

In this study, the effects of oblique running and ideal motion on the stresses of bridge crane wheels were examined. The stresses on the crane wheels were calculated using the rotation angles and the forces. The commercial finite element package I-DEAS was used for the solution of the problem. The technical values of two double girder bridge cranes with 32 and 50ton carrying capacities and 18m crane span were used. Finally, the stresses caused by the oblique running were compared with the ideal motion. The numerical results show that the stress values increase by the oblique running.

Stress analysis of adhesive bonding of urea granulator fluidization bed was performed by using finite element method. The main objective of this project is to develop an alternative joining technique for urea granulator fluidizationbed by using adhesive bonding. The problem can solve by using commercial finite element package ANSYS version 13.0. T-joint and double T-joint are the main adhesive joints which will be focused in this project. The stresses on stainless steel plate can reduce by increasing the thickness of adhesive as demonstrated in numerical analysis results. Different thickness of adhesive will give different value of maximum von Mises stress. It shows that greater thickness resulted in higher maximum. This analysis proves that increasing the adhesive thickness will reduces the joint strength because stress was concentrated more on the adhesive interfaces. The adhesive bonding on T-joint is stronger than other design of joint because it need lower stress. It followed by first design of double T-joint and second design of double T-joint.

The Ideal

Connected carbon nanotubes (CNTs) with parallel longitudinal axes and with bending angles were simulated by a commercial finite element package and their buckling behavior was investigated by performing several computational examinations. In addition, the effect of defects on the structural stability of these heterojunctions was analyzed. For this purpose, two different nanotube hybrids (straight and kink heterojunction) were constructed in their perfect forms. In the second phase, three most likely atomic defects, i.e., impurities (doping with Si atoms), vacant sites (carbon vacancy) and introduced perturbations of the ideal geometry in different amounts to the perfect models, were simulated. To conclude our study, the buckling behavior of imperfect heterojunctions was numerically evaluated and compared with the behavior of the perfect ones. It was concluded that the existence of any type of defects in the configuration of nanotube hybrids leads to a lower critical load and as a result, lower buckling properties. This study provides a better insight into the prediction of straight and kink heterojunction CNTs behavior.

Viscoelastic Bodies

It is shown how the finite-element displacement method of analysis using an elastic analogy may be applied to problems in plane stress where the material is viscoelastic. The method allows material non-homogeneity to be taken into account, as it might need to be in some thermo-viscoelastic problems. Some numerical results are given, based on the Maxwell body, and these are supported by a short-time creep experiment on a sheet of perspex. The distribution of stress is found to change slightly during this period of time.

Abstract An experimental stress-strain analysis by means of the Moiré method was conducted in the area of the tread and belt regions of tire sections. A special loading fixture was designed to support the tire section and load it in a manner simulating service loading and allowing for Moiré measurements. The specimen was loaded by imposing a uniform fixed deflection on the tread surface and increasing the internal pressure in steps. Moiré fringe patterns were recorded and analyzed to obtain strain components at various locations of interest. Maximum strains in the range of 1–7% were determined for an effective inflation pressure of 690 kPa (100 psi). These results were in substantial agreement with results obtained by a finite element stress analysis.
