Evaluation of C(t)-integral for inner cracks of steel slab during reheating process
강재의 재가열공정시 내부 균열에 대한 C(t)-적분의 평가
- Published : 1998.03.01
The crack problem of continuous casting slab due to the thermal stresses during the reheating process is analyzed using FEM. In this study, the C(t)-integral is calculated. As a result, the values of the C(t)-integral decrease by increasing the initial temperature of the slab and decreasing total heat flux. And those decrease by decreasing the heat flux of pre-heating zone and increasing the heat flux of heating zone.
