九月二十二日由我校主持,以一机部、清华、北大、北京化工学院等单位组成的专家评审组,对基础部孙燕君副教授“复合型载荷裂纹顶端的塑性问题”的科研成果进行了认真严格地审议,正式通过了技术鉴定。该研究在大量试验及数据分析的基础上,对著名的 Dugdale 条带屈服模型提出了适当的修正,较好地解决了复合型载荷下裂纹顶端塑性计算模拟问题,这是至今在断裂力
On September 22, chaired by our school, an expert review team consisting of a unit, Tsinghua University, Peking University, Beijing Institute of Chemical Technology, etc. conducted research on the scientific research achievement of Associate Professor Sun Yanjun of the “plastic problem of composite load crack tip” of the basic department. Serious and rigorous deliberations and formal adoption of technical appraisals. Based on a large number of experiments and data analysis, this study proposes appropriate corrections to the famous Dugdale belt yield model, which solves the problem of plastic deformation simulation of crack tip under complex loads.
