本文介绍了光弹性模型塑料的发展简况和国内对塑料基本性能的研究,以及几种特殊用途的光弹性模型材料,并对研制新型光弹性塑料的性能指标,提出了一些展望性的建议.一、前言光弹性模型试验成果的准确性不仅与量测仪器的精度有关,而且应该说与模型塑料性能的关系更为密切。自从本世纪二十年代以来,光弹性技术被 Coker 和 Filon 成功地用于解决工程问题以后,一直都在研究理想的新材料。 This article introduces the development of the photoelastic plastic and the domestic research on the basic properties of the plastic, as well as several special uses of the photoelastic model material, and the development of new photoelastic plastic performance index, put forward some suggestions for the future. , Foreword The accuracy of the results of the photoelastic model test is not only related to the accuracy of the measuring instrument, but also to be more closely related to the plastic properties of the model. Since the 1920s, photoelasticity technology has been used by Coker and Filon to solve engineering problems and has been working on promising new materials.
