Material Characterization of Shape Memory Alloys

形状记忆金属(SMM)是一组独特的合金，具有“记忆性”和“可训练性”。这些特性使这种材料成为用于“智能”结构或作为某些先进复合材料开发的组成部分的主要候选材料。这些材料在结构应用中的使用需要适当的本构特性。这项工作的目的是设计和进行最先进的形状记忆金属的实验，以便为正确和完整的连续介质材料表征提供信息。所测得的力学性能将构成测试、验证和校准适当理论模型的基础。

Shape memory metals (SMMs) are a unique group of alloys which exhibit qualities of "memory and "trainability." These qualities make such materials prime candidates for use in "smart" structures or as constituents in the development of certain advanced composite materials. The use of these materials in structural applications requires proper constitutive characterization. The goal of this work is to design and conduct experiments on state of the art shape memory metals in order to provide information for proper and complete continuum materials characterization. The mechanical properties measured will form the basis for testing, validating and calibrating appropriate theoretical models.
