［本站讯］11月19日下午，机械工程学院第44期研究生鼎新论坛在山东大学千佛山校区举办，来自香港城市大学的Lim教授作了题为“On Nonlocal Strain Gradient Theory of Elasticity”的学术报告。机械学院副院长李方义教授主持，学院部分老师及博士生、硕士生参加论坛。
　　李方义教授代表学院对Lim教授表示热烈欢迎，并简单介绍了近年来Lim教授在学术领域取得的成就以及同机械学院老师共同合作发展的领域。随后，Lim教授介绍了纳米断裂、非局部理论与应力问题的基本知识，以及它们与非局部弹性应变梯度理论的关系；紧接着，Lim教授介绍了自己目前研究的能量密度理论。这一理论是在原有研究基础上进行的优化，并将现有理论的研究重点向应变梯度的转变；然后，Lim教授就非局部弹性应变梯度理论的具体公式向大家进行了演绎推导，图文并茂，大家受益匪浅。
　　最后，机械学院的老师和部分研究生就非局部弹性应变梯度理论相关领域研究进行了提问，Lim教授进行了详细解答。通过这次报告，研究生对非局部弹性应变梯度理论有了一个更加深入的认识，同时拓宽了自己研究问题的思路和方法。
　　主讲人简介：Currently a registered professional engineer (RPE), Ir Prof Lim received a first degree from Univ. of Technology of Malaysia, a Master’s Degree and PhD from National University of Singapore and Nanyang Technological Univ., respectively. Prior to joining City U, he was a post-doctoral research fellow at Department of Civil Engineering, The University of Queensland and Department of Mechanical Engineering, The University of Hong Kong. Prof. Lim is also a visiting professor at various universities including the University of Western Sydney, Dalian University of Technology, etc. He has expertise in vibration of plate and shell structures, dynamics of smart piezoelectric structures, nanomechanics and symplectic elasticity. He is the Associate Editor (Asia-Pacific Region) for Advances in Vibration Engineering (SCI-listed journal), Guest Associate Editor for International Journal of Bifurcation and Chaos, and also on the editorial board of a few other international journals. He has published one of the best-selling titles in Engineering Mechanics entitled “Symplectic Elasticity” and co-authored with W.A. Yao and W.X. Zhong, as recorded in April 2010 by the publisher, World Scientific. He has published more than 200 international journal papers, accumulated more than 2000 independent citations, and one of the papers was granted the IJSS 2004-2008 most cited article award. He was also awarded Top Referees in 2009, Proceedings A, The Royal Society.
