Material Characterization of Shape Memory Alloys

9503633 Abeyaratne该奖项是研究形状记忆合金的理论与实验相结合的计划的一部分，形状记忆合金是一类具有“记忆”和“可训练性”的材料。 这个程序将涉及循环和双轴载荷和温度从-70到1500 ℃以及更高的应变率。 研究的主要目的是研究马氏体退孪晶对相变应力的依赖性，以及马氏体退孪晶对多轴应力状态的抵抗性。 特别强调的是双轴应力状态，其中不均匀变形，这是固有的不稳定性，发生。 ***

9503633 Abeyaratne This award is part of a combined theoretical-experimental program to study shape memory alloys, a class of materials that have qualities of "memory" and "trainability". This program will involve cyclic and biaxial loads and temperatures from -70 to 1500 C as well as higher strain rates. The main goals of the research are to study the dependence on the transformation stress, and the resistance of martensite detwinning to multiaxial states of stress. Special emphasis will be given to biaxial states of stress where inhomogeneous deformations, which are inherently associated with the instability, occur. ***
