Abstract

Abstract:

Three damage variables D(E), D(A) and D(Ra) were defined from macroscope and mesoscope respectively. The D ε curves of the same damage process in the tension of LY12CZ board specimen were analysed both individually and by contrast. The results showed: The D ε curves varied as power functions; The correlativity of macro with meso variables was closed. In addition, the changing of D(A) and D(Ra), which were defined by the surface parameters, was earlier than that of D(E), which was defined by the whole parameter.

Key words: corr elat ivity, macro-and meso-damage var iable, the same damage pr ocess
