第四届多火花动态光弹性研讨会于1991年10月29至31日在南京华东工学院举行。来自全国十个单位的23位代表参加了会议,其中76岁高龄的实验力学前辈、中国力学学会实验应力分析专业委员会原主任委员傅梦蘧高级工程师,以及各方面从事动态光弹性工作的专家,中国科协学会部董正同志也出席了会议。代表们在会上报告了本单位的近期工作进展、经验及体会;总结了近年来动态光弹性工作的现状,并就共同关心的实验设备、加载方式及其测定、条纹判读、主应力分离、模型律等八个重点问题作了专题讨论。
The 4th Multi-Spark Dynamic Photoelastic Symposium was held at East China Institute of Technology in Nanjing on October 29-31, 1991. Twenty-three delegates from ten units attended the conference. Among them, 76-year-old experimental mechanics predecessor, former director of Experimental Stress Analysis Committee of Chinese Society of Mechanical Engineering, senior engineer Fu Mengxun, and experts engaged in dynamic photoelasticity work in all aspects, Dong Zheng Association Association also attended the meeting. At the meeting, the delegates reported the progress, experience and experience of their recent work. The status quo of dynamic photoelasticity work in recent years was summarized and the common interest in testing equipment, loading methods and determination, streak interpretation, separation of principal stress, Model law and other eight key issues made a special discussion.
