XFEM Simulation of Channeling Crack Propagation in a Thin Film/Substrate System

碩士 === 元智大學 === 機械工程學系 === 100 === The extended finite element method (XFEM)is extended from the conventional finite element method. In the simulation of crack growth, it does not need a clear definition of the fracture surface and does not have to be remeshed. In the present work, the extended fin...
