本文概述了考虑微观结构的连续介质力学和金属微观断裂模型的进展,指出必须建立金属微观组织尺度,才能将断裂力学有效地应用于金属断裂的微观过程,才能彻底解决钢的强韧化问题。
In this paper, the progress of continuum mechanics and microstructural fracture models considering microstructures is summarized. It is pointed out that microstructural scales must be established to effectively apply fracture mechanics to the microscopic process of metal fracture, so that the toughness of steel can be completely solved.
