CAREER: Experimental Mechanics and Modeling of Interactive Solids and Structures

提出的研究工作包括表征和模拟表现出强多场相互作用的非经典材料的行为。特别是，最近对某些形状记忆合金的实验已经显示出应变局部化和微妙的热-力学相互作用，对此尚无明确的模型可用。这些实验的范围将扩展到包括循环加载、多轴加载和更高的应变率。目标是发展基于热力学的模型，承认与这些实验一致的不稳定力学行为的可能性。这项工作的教育成分将通过设计/建造项目和新开设的课程培养本科生和研究生对这些非经典材料的认识。

The proposed research consists of work to characterize and model thebehavior of nonclassical materials exhibiting strong multi-fieldinteractions. In particular, recent experiments of certain shape memoryalloys has shown strain localization and subtle thermo-mechanicalinteractions, for which no definitive models are yet available. The scopeof these experiments will be extended to include cyclic loading,multi-axial loading, and higher strain rates. The objective will be todevelop thermodynamically based models that admit the possibility ofunstable mechanical behavior consistent with these experiments. Theeducational component of this work will foster undergraduate and graduatestudents' awareness of these non-classical materials through design/buildprojects and new offered classes.
