题目：The Duality of
Strength and Ductility in Graphene-Metal Nanocomposites under Tensile Loading
摘要：本报告提出了一种考虑塑性与损伤的多尺度统一理论，有效地解释了石墨烯纳米复合材料中高强度-低塑性的两难现象。该理论已经成功应用于石墨烯/铜纳米复合材料。

题目：Maxwell-Wagner-Sillars mechanism in Graphene-Polymer Nanocomposites
摘要：本报告通过发展一种等效介质理论，研究了众多纳米电容器中石墨烯/多聚物界面中Maxwell-Wagner-Sillars (MWS)效应对纳米复合材料性能的影响。理论预测与实验测量结果对比表明MWS机理确是石墨烯/多聚物纳米复合材料电导率与介电常数依赖于频率的主要原因。
报告人简介：
Professor George Weng is a Distinguished Professor
at Rutgers University. He received his B.S. from National Taiwan University in
mechanical engineering in 1967 and Ph.D. from Yale University in engineering
and applied science in 1974. He worked at Delft University of Technology, UCLA,
and GM before joining Rutgers in 1977 as an Assistant Professor. He was
promoted to an Associate Professor in 1980, Full Professor in 1984, and Distinguished
Professor in 1992. His research interests are in the general areas of solid
mechanics that connect the underlying deformation mechanisms to the overall
behavior of materials. Over the years his works have touched upon the
plasticity of single crystals and polycrystals, micromechanics of composite
materials, shape-memory alloys, ferroelectric ceramics, magnetoelectric
coupling, nanocrystalline solids, and electrical and thermal conductivity of
CNT- and graphene-based nanocomposites. He has published 226 referred journal
articles, written 8 book chapters, and edited 5 books. His Google Scholar
citations are 9,552 with an h-index of 50, and Web of Science citations are
6,295 with an h-index of 42. He has been an Editor of Acta Mechanica since 1985,
and was the Editor of Journal of Engineering Materials and Technology from
1992-1997. He also served as Chairman of ASME Materials Division during
1993-1994. He is a Fellow of ASME, a Fellow of American Academy of Mechanics,
and an Honorary Life Member of Society of Engineering Science. In recognition
of his fundamental contributions in theoretical solid mechanics, he was awarded
the prestigious William Prager Medal in 2013.
