基础部副教授孙燕君一九八三年在美国期间发表了“动态曲裂的进一步研究“论文后,于一九八三年十一月二十五日又参加了在北京召开的国际断裂力学会议。在会上发表了“复合型载荷下裂纹顶端的塑性问题”论文,受到各国专家的好评。并被选入大会出版的《国际断裂力学学术会议论文集》中。这项研究建议裂纹尖端张开角度可以作为聚碳酯酸断裂试件的一个新的稳定裂纹扩展判据。
In 1983, Associate Professor of the Basic Department Sun Yanjun published the paper on “Further Research on Dynamic Quasi Cracking” in the United States. On November 25, 1983, he joined the International Conference on Fracture Mechanics held in Beijing. At the conference, he published a paper on “The Plasticity of Crack Tips under Compound Loads,” which was well received by experts from various countries. And was selected into the “Proceedings of the International Conference on Fracture Mechanics” published by the General Assembly. This study suggests that the opening angle of the crack tip can be used as a new criterion for stable crack propagation of the fracture specimen of the polycarbonic acid.
