利用形状记忆合金降低结构的应力集中研究

Shape Memory Alloy for Stress Concentration Reduction in Adaptive Structures

形状记忆合金（ＳＭＡ）由于具有形状记忆效应（ＳＭＥ），可以用于改善承载结构中受损伤部位的应力、应变分布，降低危险区域的应力集中。本文介绍了这项新技术。

This paper presents a new technique of using Shape Memory Alloy(SME),which has unique Shape Memory Effect (SMA),to improve the stress distribution of damaged structures and reduce the stress concentrations.The theoretical and experimental studies of an isotropic plate with a hole have been conducted to demonstrate the feasibility of this technique.
