Abstract
A global-local analysis method is demonstrated within the Regularized eXtended Finite Element (Rx-FEM) framework. Rx-FEM is a Discrete Damage Modeling (DDM) method for progressive failure analysis, which introduces displacement discontinuities to represent matrix cracks and delaminations within composite materials. The global-local approach allows for the damage analysis of a localized region within a much larger domain for which stress analysis has already been performed. Two different case studies including static and fatigue analysis were addressed in this work. Results demonstrate that the global-local approach reduces the computational cost in comparison to high fidelity large scale structural analysis and produces reliable results. The present framework is limited global to local scale communication only.
