第四届多火花动态光弹性研讨会于1991年10月29日至31日在南京华东工学院举行。来自全国10个单位的23位代表参加了会议,其中有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付梦蓬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。华东工学院院长李鸿志教授参加了开幕式,代表们在会上报告了本单位近期的工作进展,经验及体会;会上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 from October 29 to 31, 1991. Twenty-three representatives from 10 units attended the conference. Among them, 76-year-old experimental mechanics predecessor, former chairman of Experimental Stress Analysis Committee of Chinese Society of Mechanical Engineering, Fu Mengpeng, senior engineer and experts involved in all aspects of dynamic photoelasticity work, Chinese Association for Science and Technology Association Dong Zheng also attended the meeting. Professor Li Hongzhi, Dean of East China University of Science and Technology, attended the opening ceremony. Delegates reported on recent work progress, experiences and experiences of their own units. They summed up the status quo of dynamic photoelasticity work in recent years and gave suggestions on the experimental equipment , Loading method and measurement, streak interpretation, separation of main stress, model law and other eight key issues were discussed.
