Abstract:

In this talk, a novel approach for the efficient automation of numerical modeling processes directly from CAD models and digital images will be presented.A general n-sided-polygon element based on the concept of the scaled boundary finite element method, will be introduced. Its performance will be demonstrated with examples of fracture analyses (static, dynamic, elasto-plastic, functionally graded materials and crack propagation).This n-sidedpolygon element combines ideally with a quad tree mesh for the automation of the numerical modeling 

process from CAD models and digital images. The accuracy, efficiency and robustness of the proposed technique are demonstrated with numerical examples. Potential research and applications of this novel technique in structural and material modeling will be discussed.
