Abstract

This article provides experimental and numerical data for the propagation of stress-induced martensitic transformation within NiTi structures with uniform and nonuniform geometries. This article is related to the research paper entitled "Computational and experimental analyses of martensitic transformation propagation in shape memory alloys" [1]. The heterogeneous transformation evolutions within geometrically graded NiTi structures are presented by thermal images recorded by a high-resolution infrared camera during tensile loading. The modelling of transformation and deformation behaviours of those structures is presented by finite element computational method.

摘要

本文提供了应力诱导马氏体相变在具有均匀和非均匀几何形状的镍钛结构中传播的实验和数值数据。本文与题为《形状记忆合金中马氏体相变传播的计算与实验分析》[1]的研究论文相关。在拉伸加载过程中，通过高分辨率红外相机记录的热图像展示了几何梯度镍钛结构内的非均匀相变演变。通过有限元计算方法对这些结构的相变和变形行为进行了建模。
