一、引言遵照毛主席“我们必须打破常规,尽量采用先进技术,在一个不太长的历史时期内,把我国建设成为一个社会主义的现代化的强国”的教导,我们开展了激光全息光弹性的研究。本文是全息光弹在平面问题中的实验研究结果,并对试验设备及试验技术加以某些说明。半个世纪以来,古典光弹性方法在工程结构及机械零件强度研究中,已经得到广泛的应 I. INTRODUCTION Following Chairman Mao’s teachings that “we must break the routine, try to adopt advanced technologies and build our country into a powerful modern socialist nation in a not too long historical period,” we have launched a laser holographic photoelastic the study. This article is the result of an experimental study of holographic photoelasticity in a plane problem and gives some explanations on the experimental equipment and experimental techniques. For half a century, the classical photoelastic method has been widely used in engineering structure and mechanical parts strength research
