报告题目: Development and application of a hybrid finite-discrete element method for investigating dynamic fracture of rocks under impact loads as well as geohazard mitigation and prevention
摘要: Combined finite-discrete element method (FDEM) incorporates the advantages of the continuous and discontinuous methods and thus can seamlessly model the transition from continuum to discontinuum during material damage and fracture. Correspondingly, FDEM has been applied and further developed by a number of researchers around the world for various engineering applications involving in the damage and fracture of a range of materials. A both two-dimensional (2D) and three-dimensional (3D) hybrid finite-discrete element method (HFDEM) has been developed at University of Tasmania (UTAS) for the failure and collapse analysis of geostructures, which has also been parallelized on the basis of general-purpose graphic-processing-units (GPGPU) using compute unified device architecture C/C++. This presentation will introduce the method and its applications in rock and soil engineering.
