The Second Workshop on Recent Progress of the Scaled Boundary Finite Element Method (SBFEM2018)

Faculty of Infrastructure Engineering, Dalian University of Technology, Dalian, China

Nov. 3-5, 2018

INTRODUCTION

Objectives

The scaled boundary finite element method (SBFEM) has been developed into a general purpose numerical method since it was first proposed by Song and Wolf in 1996 for the solution of wave propagation problems. This method is semi-analytical and only the boundaries of the subdomains are discretized. Its advantages were firstly recognized for the modelling of problems involving unbounded media and singularities. Recently, a methodology for constructing arbitrary polygon/polyhedron elements for linear and nonlinear analyses was established based on the SBFEM. This development theoretically renders the range of application of the SBFEM as wide as that of the displacement-based finite element method. Today, the application of the SBFEM has been expanded to many other important fields in engineering, such as fluid mechanics, dam-reservoir-foundation interaction, electromagnetics, ultrasonic guided waves problem,fracture problem, acoustics, seepage, electrostatics, linear and nonlinear geotechnical problems, sensitivity analysis and heat transfer, etc. However, great potential of the SBFEM in modelling 3D microstructures of concrete or composite materials, crack propagation, dynamic contact for cracks analysis, shell problems, dam-reservoir-foundation interaction, interaction of complex soil and pile foundation,large scale computing problem, fastmesh generation problem, moving boundary problems, etc. remains to be explored.

In order to summarize new developments, advances and applications of the scaled boundary finite element method and provide a floor for the mutual exchange of ideas on the SBFEM for the interested research all over the world, The First Workshop on Recent Progress of the Scaled Boundary Finite Element Method (SBFEM2017) has been successfully held in Hohai University, Nanjing on Nov. 5-7, 2017, the second workshop (SBFEM2018) continuing the previous and successful workshop will be held in Dalian University of Technology on Nov. 3-5, 2018.
