Abstract: Based on the experimental results of local temperature field and pyromagnetic effect at the process zone of the crack-tip formed in the evolution period of defects, in this paper, the expressions of thermo-mechanical coupling and thermo-elect romagnetic coupling effects in the basic equation group of rheological material containing defects are first proposed.

Key words: rheological material containing defects, basic equation group, process zone of the crack-tip, thermomechanical coupling effect, thermo-elect romagnetic coupling effect
