中文摘要
本项目的目的是研究相变诱发塑性(TRIP)和发展钢断裂的本构规律。该研究将验证多轴应力状态下的本构关系,并评估相变对具有宏观裂纹的固体的韧性增强。本研究的结果将很有可能将陶瓷增韧的概念扩展到金属,并提高对金属弹塑性断裂力学的基本认识。
英文摘要
The objective of this project is to study transformation-induced plasticity (TRIP) and develop constitutive laws for the fracture of steels. The research will verify the constitutive relationships for multiaxial states of stresses and evaluate the toughness enhancement in a solid with a macroscopic crack as a result of the phase transformation. The results of this study will have a good potential to extend the concepts developed in the transformation toughening in ceramics to metals and improve the fundamental understanding of elastic-plastic fracture mechanics of metals.
