欢迎广大师生参加！报告简介：
The scaled boundary finite element method (SBFEM) is a semi-analytical technique that exhibits unique advantages in modelling fracture phenomena. This presentation demonstrates the development of the SBFEM to address fracture problems in engineering from two different aspects; (i) discrete fracture modelling techniques and (ii) diffused modelling techniques. In the discrete fracture approach, the advantages of the SBFEM to accurately compute the stress intensity factors, efficient remeshing using polygons and quadtree meshes are exemplified. In the diffused modelling approach, a phase field-based framework is presented. An adaptive remeshing approach using quadtree meshes enables efficient deployment of the phase field method with the SBFEM, alleviating the need to use very fine meshes over the entire domain. Extensions of the phase field method based on the SBFEM to model fracture and damage phenomena described by MultiPhysics processes, e.g., hydraulic fracture, thermoelastic fracture and hydrogen-assisted stress cracking will be demonstrated.
