Abstract

This study was presented the assessment of multiaxial fatigue criteria of cylinder head for a free piston linear engine using finite element analysis techniques. The structural solid modeling of cylinder head was developed utilizing the computer-aided design software. The finite clement modeling and analysis were performed utilizing the finite element analysis codes. The biaxiality analysis was performed lo assess the multiaxial fatigue. The material parameter and Hoffmann-Seeger methods were considered to modify the uniaxial material properties. Prediction of fatigue life, effect of the stress combination for the proportional loading condition was investigated in this study. It can be seen that the biaxiality correction method gives conservative predicted life as compared to the uniaxial loading. The materials parameter correction method gives most conservative prediction with SWT criteria. It is also observed that more conservative prediction to use Signed Tresca parameter and Signed von Mises stress gives the result that lie between the absolute maximum principal and signed Tresca results. This approach shows to be quite suitable for integration with a commercial finite element code to provide for an integrated design environment for fatigue life evaluation under general multiaxial loading conditions.
