Abstract
A Total-Lagrange formulation for geometric nonlinearity was implemented within the Rx-FEM framework. Rx-FEM is a discrete damage modeling method for progressive damage analysis which introduces displacement discontinuities to represent matrix cracks and delaminations in composite materials. The effects of geometric nonlinearity on other Rx-FEM material nonlinearities were then demonstrated by leveraging the formulation against a twocell frame demonstration problem. Geometric nonlinearity was shown to enable the simulation of buckling of the composite laminate, which was significantly influenced by the presence and growth of matrix cracks.
