本刊从国家自然科学基金委员会获悉:材料与工程科学“七五”重大项目近期取得的一批重要成果,为我国材料与工程科学理论水平及其工程应用水平的提高作出了积极贡献。1.金属断裂规律及机理若干问题的研究在学部委员肖纪美教授主持下,组织150多位科研人员对材料断裂学科中带有普遍意义的静载断裂、疲劳损伤和疲劳断裂、氢致开裂等三种断裂的规律及机理进行研究,从而取得了一批重要成果。如在静载断裂方面,对弹塑性材料裂纹顶端高阶渐进场,扩展裂纹渐进场和
This issue from the National Natural Science Foundation of China was informed that material and engineering science “75” major projects recently made a number of important achievements for the material and engineering science theory level and its engineering application level to make a positive contribution. 1. Metal rupture law and mechanism of a number of issues under the auspices of Professor Xiao Jimei, member of the academic department, organized more than 150 researchers in materials fracture discipline with a general sense of static load fracture, fatigue damage and fatigue fracture, hydrogen cracking and other three Kinds of fracture rules and mechanism of research, which has made a number of important achievements. As in the static load fracture, the crack tip of elastoplastic high-order asymptotic field, crack growth field and
