열에너지를 고려한 파괴인성치 고찰
Evaluation for Fracture Toughness with Considering the Thermal Energy
초록
In the case of a crack propagation a portion of the work of inelastic deformation near the crack tip is dissipated as heat. In order to understand the thermal effect on fracture toughness, tensile tests were carried out using thermocouples to monitor the variation of temperature. The experimental results show that the temperature of specimen was increased
