Discussion of Nonlinear Constitutive Models for Aluminium Alloy Material Engine Piston

Article Preview

Abstract:

The engine piston is the critical component of the automobile, which always show high nonlinear behaviours under the thermal and mechanical cycling load. By contracting known metal material’s common constitutive theory、analyzing its composition method of continuous function and considering the special requirements of engine piston runs in the high temperature environment, the thesis could find a practical constitutive model which is applicable for aluminum alloy material used on engine piston. Through ways of analyzing and contracting, the constitutive model proposed by Sehitoglu proved to be applicable.
