综合介绍 General Introduction 主要从事航空材料与结构在冲击载荷下力学行为测试、分析等方面的研究工作，主要研究方向为结构冲击响应与破坏，主要科研成果包括航空铆钉/螺栓连接结构动态力学及失效行为、复合材料结构高速冲击响应、金属材料动态本构模型及失效参数获取方法等，为国防、民用航空领域的动态冲击试验及数值仿真提供了亟需的测试及研究手段。 个人相册 教育教学科学研究 Scientific Research 一、冲击载荷下铆钉/螺栓连接结构力学行为和失效准则 铆钉/螺栓连接在现代大型飞机上应用极为广泛，其在服役过程中时常会发生动态失效，特别是当受到鸟类、冰雹等离散源的冲击时。全面认识载荷速率和载荷状态对铆钉/螺栓连接结构力学行为的影响，并在此基础上建立动态失效准则，对飞机结构抗冲击设计具有重要的科学意义和工程价值。二、复合材料结构高速冲击响应 碳纤维增强树脂基复合材料的高速冲击响应和损伤机理远比金属材料更为复杂，发展高精度弹道冲击试验技术及数值仿真技术，进而深入探究纤维及树脂性能、铺层角度、撞击物及接触方式等多种影响因素对复合材料高速冲击响应特性的影响规律，对我国大型商用航空涡扇发动机复合材料机匣结构的优化设计和结构验证具有十分重要的意义。三、金属材料动态本构模型及失效参数获取方法 爆炸和高速碰撞分析中的诸多物理现象，如应力波和冲击波的传播、材料崩落、厚靶成坑、中厚靶的侵彻与充塞、薄靶鼓包、碎片的形成及演化等，都是材料的大变形和断裂的过程。准确描述材料弹塑性响应及失效过程的应变率效应、应力状态、应变硬化和温度软化等效应是实现动力学瞬态仿真分析的前提。 荣誉获奖学术成果 Academic Achievements 近5年代表性论文[1] Tengfei Ren, Cunxian Wang*, Bing Hou, Xinyue Zhang, Tao Suo*.
