Simple Global-Local one-way coupled finite analysis for finite deformation elastoplastic fracture mechanics analysis

In this study, we propose a one-way coupled analysis method for finite strain elastic-plastic analysis, assigning displacements at a global finite element analysis method analysis assuming cracks to a local finite element analysis. The proposed method uses the least-squares method to smooth out the nodal displacements of the global finite element analysis, they are arranged to surface nodes of the local finite element model as displacement boundary conditions. We investigated identify the application conditions that can assure accuracy of present global-local analysis.
