个人简介

魏悦广，中国科学院院士，北京大学博雅讲席教授。北京大学工程科学与新兴技术高精尖创新中心主任及先进与设计制造部PI。本科毕业于西安科技大学，博士毕业于清华大学工程力学系固体力学专业。后于北京大学及美国哈佛大学从事博士后研究工作。长期从事跨尺度力学、弹塑性断裂力学、复合材料力学等研究。在国际上建立了协同考虑应变梯度和表界面效应的跨尺度力学理论；建立了可压缩应变梯度理论并由此预测出金属的微尺度断裂强度高达其宏观屈服强度十倍以上的重要结论，突破了传统力学理论的预测极限，引起跨尺度力学研究在国际上的广泛开展。近年来，将跨尺度力学理论成功应用于发动机叶片先进热障涂层强韧及破坏机制的表征。相关成果共发表学术论文300多篇，受到国内外同行的广泛引用，连续5年入选爱思唯尔中国高被引学者，获国家自然科学奖二等奖2项和三等奖1项。长期参与学会工作，近20多年间先后担任副秘书长、理事、常务理事、固体专委会副主任、主任、力学学报主编等工作。
