Research Initiation: Constitutive Laws Under Multiaxial States of Stress and the Fracture Mechanics of TRIP and Austenitic Steels

本项目的目标是研究转型诱导 塑性（TRIP），并制定本构关系的断裂 钢. 本研究将验证本构关系， 多轴应力状态并评估韧性增强 由于相的存在而产生宏观裂纹的固体 转型 本研究成果将具有良好的应用前景 为了扩展相变增韧中发展的概念， 从陶瓷到金属，提高对 金属弹塑性断裂力学

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.
