Abstract:
In this paper, based on Lemait re’ s local status dynamic coupling theory, the damaging process of brit tle and duct ile materials such as ceramic, stainless steel and aluminum alloy is simulated by using finite element method and post processor prog ram. At the same t ime, the material crack imitation process is analyzed according to character of damage in mesosize act ived in defferent loading, thus of fering the method to predict the damage material life.
