报告简介：

With the rapid progress of computers and other digital technology, computational analysis has become indispensable in tackling large-scale complex problems faced by modern engineering and in the digital transformation of industry. This talk presents our recent research towards developing a computational framework that fully automates the engineering analysis process directly from commonly used formats of digital geometric models. Our approach is underpinned by the scaled boundary finite element method, which enables us to incorporate an octree algorithm for automatic mesh generation across various formats such as digital images, STL models, point clouds and traditional CAD models. Furthermore, the solution procedure is purposely designed for the scaled boundary finite element method to leverage modern computer hardware architectures for high-performance computing. Numerical examples and demonstrations illustrate key features and the potential of the proposed framework for simulating complex 3D models, accounting for material and geometric nonlinearities, fractures, and contacts.

报告人简介：

Prof. Chongmin Song(宋崇民)，澳大利亚新南威尔士大学土木与环境工程学院教授，基础结构安全中心主任。Song教授主要从事比例边界有限元、断裂力学、波动传播、地震工程与结构动力学等方面的研究。1996年他与瑞士联邦理工学院的Wolf J.P.教授共同创立了比例边界有限元法（Scaled Boundary Finite Element Method, SBFEM）。这种新型数值方法兼具了有限元法与边界元法的优点同时又避免了其缺点，其主要特点包括精度高、计算量节省，并且在处理无限域问题和应力奇异性方面具有突出优点。近年来在Computer Methods in Applied Mechanics and Engineering、Computers & Structures、Computational Mechanics、International Journal of Solids and Structures、Earthquake Engineering and Structural Dynamics等国际著名期刊上发表论文200余篇，独著《The Scaled Boundary Finite Element Method: Introduction to Theory and Implementation》（2018，Song Ch.）、合著《Finite-Element Modelling of Unbounded Media》（Wolf J. P. and Song Ch., 1996）、《The semi-analytical fundamental-solution-less scaled boundary finite element method to model unbounded soil》（Wolf J. P. and Song Ch., 2003）两部。至今主持澳大利亚自然基金等项目20余项。
