热弹性马氏体相变塑性─—细观力学本构模型、实验和数值模拟

THERMOELASTIC MARTENSITIC TRANSFORMATION INDUCED PLASTICITY---MICKOMECHANICS MODELLING,EXPERIMENT AND SIMULATIONS

热弹性马氏体相变塑性是形状记忆合金变形特性和一些脆性结构陶瓷因裂纹尖端屏蔽而增韧的机理之一。本文回顾和总结有关热弹性马氏体相变材料（如形状记忆合金和含二氧化锆陶瓷）细观力学本构关系以及相变增韧研究的重要进展。着重评述最近在上述领域（尤其是中国学者）取得的成果。

Thermoelastic martensitic transformation induced plasticity(TMTRIP)is responsible for thebehaviour of shape memory alloys and is also one of the basic mechanisms for crack tip shielding,i. e. ,tougheningof some brittle structural ceramics.This review article attempts to organize and summarize the important researchdevelopment in the area of constitutive relations and fracture of the martensitic phase transforming materials suchas zirconia-containing ceramics and shape memory alloys.Prime concern is paid to the micromechanics constitutivedescription of the TMTRIP phenomena and its relations with transformation toughening. Recent advances in thisarea are emphasized,especially those in China.
