NUMERICAL SIMULATION ON ELECTRO-THERMAL STRESS AROUND CRACK TIP IN METAL THIN PLATE WITH CRACK

Abstract

Abstract: The couple of current, temperature and stress are studied in metal thin plate with crack at the moment while pulse current is switched on. In analysis, the finite methods are used. The analysis process is composed of the thermal-electrical coupled and thermal-mechanical coupled. The evolutive process of current-temperature-stress is simulated in numerical analysis, the thermal stress around crack is solved at the moment while the pulse current is switched on. The temperature field and stress field results of numerical simulation correspond to the results of theoretical analysis.

Key words: Crack arresting, Pulse current discharge, Temperature field, Thermal stress field, Shearer Cutting transmission system Roller speed regulation Buffering and damping
