应569vip威尼斯游戏应用力学研究所的邀请，以色列特拉维夫大学（Tel Aviv University）Diane & Arthur Belfer讲座教授Leslie Banks-Sills访问我所，并于6月24日上午10:30在569vip威尼斯游戏玉泉校区教12-118会议室作了题为“Interface Fracture of Homogeneous Materials and Laminates – Theory and Experiment”的学术报告。
断裂力学是上世纪中期发展起来的固体力学的一个新的分支学科，考虑了固体或结构中固有缺陷的影响，克服了传统强度理论的不足，为船舰、飞机、大型基础设施等现代工程的可靠性设计和寿命评估奠定了重要理论基础。
Banks-Sills教授在报告中介绍了其课题组在界面裂纹分析方面的系统研究，包括传统的两相均匀材料的界面裂纹和现代复合材料的界面裂纹。她阐述了通过引进特定的长度参量以规避界面裂纹尖端应力强度因子的“奇怪”量纲的研究思路，并从实验上予以了证实。这一长度参量不依赖于具体的裂纹长度，但与断裂模式（即I型、II型或III型）有关，可能属于一种内廪的材料尺寸，其具体的物理意义还需要进行深入的研究。Banks-Sills教授还介绍了其课题组在压电陶瓷断裂方面的研究工作，并期望能够在压电陶瓷的三维断裂研究上与应力所相关教师进行合作。
报告吸引了众多老师和同学参与，引起了热烈的讨论。Banks-Sills教授在正式报告之前也介绍了以色列的大致情况，使在座的师生有了更好的了解。
附：报告人简介
Professor Leslie Banks-Sills holds the Diane and Arthur Belfer Chair of Mechanics and Biomechanics at Tel Aviv University since November 2006. She is a Guest Professor at Lund University where she held the Lise Mietner Chair in 2006 and an Adjunct Professor at Cornell University. She serves on the editorial boards of Engineering Fracture Mechanics, International Journal of Fracture, International Journal of Structural Integrity and Strain. She has consulted for various organizations in Israel, as well as for NASA, regarding problems of fracture in structures.
Professor Banks-Sills completed a B.A. degree in mathematics at Queens College of the City University of New York in 1965, an M.Sc. degree in engineering mechanics from the University of Michigan in 1973 and a Ph.D. degree in engineering from Harvard University in 1977. After carrying out a post-doctorate at Brown University, she joined the Faculty of Engineering at Tel Aviv University in 1979. From 1993 through 1997, and again from 2001 through 2005, she served as Chairman of the Department of Mechanics, Materials and Structures. She is Director of the Dreszer Fracture Mechanics Laboratory at Tel Aviv University.
She received the Teaching Excellence Award in Mechanical Engineering, Tel Aviv University (1995-1996), the Teaching Excellence Award, Faculty of Engineering, Tel Aviv University (1998-1999), and the Teaching Commendation Award in Mechanical Engineering, Tel Aviv University (2010-2011). She was elected as an Honorary Fellow of the International Congress of Fracture in 2005 and served on the Executive Board of this organization. The Technion in Haifa awarded her the Hanin Prize for her contributions to aeronautical engineering in 2006. She is the recipient of the 2006 Honorary Membership to ESIS (European Society of Structural Integrity) for her outstanding original technical contributions to fracture mechanics and good service to the international fracture mechanics community. She was elected as a Fellow of the American Academy of Mechanics in 2008. In 2006, she was elected one of two Vice Presidents of ESIS and is currently the President (2010-2014). In addition, she is a Vice President of EURASEM (European Society of Experimental Mechanics) since 2008.
Her research interests include the use of analytical, numerical and experimental methods to treat fracture problems which include homogeneous materials, bonds, interfaces and composites. In particular, recently she and her group have been examining the propagation of cracks in piezoelectric materials, delamination of cross-ply and woven composites and the effect of carbon nano-tubes in polymer materials.
She has participated in over 60 international conferences and been on the scientific committees of many of them. She has guided over 40 Master’s, Ph.D. and post-doctoral students many of whom hold key positions in academia and industry. She has published over 100 papers in international journals and edited the book Advances in Mathematical Modeling and Experimental Methods for Materials and Structures, The Jacob Aboudi Volume, Springer, The Netherlands (2010) with Dr. Rivka Gilat.
