| Abstract: | In this paper, based on Lemaitre's local status dynamic coupling theory,the damaging process of brittle and ductile materials such as ceramic, stainless steel and aluminum alloy is simulated by using finite element method and post processor program.At the same time, the material crack imitation process is analyzed according to character of damage in mesosize actived in defferent loading,thus offering the method to predict the damage material life. |
