摘　　要：以应力测定中的几个关键问题为研究对象,综述了线性应变和平面应变状态下应变测量及应力计算方法。主要对平面应力状态下应变测试和应力求解技巧、电阻应变仪选择和测试点及应变片布置问题进行讨论,并归纳了几种应变花法计算主应力的通用公式,可为工程结构设计和实验验证提供参考。Taking a few of key questions as objects of study, it sums up the methods of strain gauging and stress calculation for component bearing linear strain or plane strain state. The emphasis of this discussion is on the technique to solve stress and test strain for plane stress state, methods of choosing strain meter and arrangement of testing points and strain piece. Finally, it summarizes formula be in common use to calculate main stress via measuring strains in several methods, which can supply reference for designing engineering structure and experimental verification.
