Abstract
The scaled boundary finite-element method is a semi-analytical method based on finite element technologies and presents additional appealing features of its own. This method is known to be particularly attractive in modelling problems with unbounded domains or singularities as it handles infinity analytically. It has recently been recognized that this method offers a high degree of flexibility in mesh generation. Preliminary investigation has illustrated its great potential in developing a fully automated process of engineering analysis directly from geometrical models.
This presentation will start with a brief theoretical background of the scaled boundary finite element method so that the salient features of this method can be appreciated. Some recent advances in the fundamental theory are summarized. Applications in the areas of dynamic soil-structure interaction, acoustic fluid-structure interaction, fracture mechanics, elasto-plasticity, piezoelectric composites, Lamb waves, and plate analysis will be presented to demonstrate the accuracy and efficiency of this general-purpose numerical technique in solving problems challenging to standard numerical methods. The current research activities of the speaker’s group on the development of a full automatic procedure for computer simulations directly from geometrical models, such as CAD, STL and digital images will be introduced. Challenges and directions of further developments will be discussed.
Key words: Scaled boundary finite element method, Polytope element, Mesh generation, Fracture analysis, Numerical method
