Finite Element Analysis and Optimization Design of Automobile Exhaust Pipe Lifting Lugs

Experimental and finite element vibrational analysis of exhaust manifold heat shield

Most of internal combustion engines have one or two heat shields that have been installed on the exhaust manifold to avoid the heat transfer to upper parts of the engine such as the valve cover. In some engines, this part fails due to the fracture and causes engine noise and other failures in the engine. In this paper, the failure of a heat shield due to vibrational loads of the engine has been...

Design Optimization of Hip Resurfacing Prosthesis Using Finite Element Analysis

Hip resurfacing is an alternative to total hip arthroplasty for the young and active patient likely to outlive traditional means of hip joint replacement. To optimize design on the hip resurfacing prosthetic stress profile in the proximal femur after hip resurfacing. The acetabular cup is implanted in much the same fashion as an uncemented total hip arthroplasty, however, implantation of the fe...

Design & Optimization of a Rim Using Finite Element Analysis

On Finite Element Analysis of Pipe Whip Problems

The nonlinear dynamic finite element solution of pipe whip problems is presented. The finite element modelling used, the step-by-step incremental solution of the nonlinear equations of motion and design considerations are discussed. The influence of various physical parameters on the response of the pipe and the restraint, and the effects of using different finite element models are considered....

Non Linear Finite Element Analysis of Reinforced and Unreinforeced Pavements

In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...
