Abstract
A finite element Macro Model is proposed for the analysis of continuous and discontinuous 3D fiber-reinforced polymer composites (FRPCs). The Macro Model is made by modeling the matrix and each fiber layer as a parallel and geometrically similar elements, respectively. The yield strength of the material is modeled by an elastic-plastic Mises material with linear work-hardening. The fiber yielding is modeled by an additional negative work-hardening curve with values approaching that of its Young’s modulus to simulate failure after the maximum plastic strain is reached. A series of case studies is used to illustrate the facets of the model and compare the results with experiment. In most cases, and using carbon fiber, it was found that premature failure occurred by fracture. A fracture analysis model was proposed as an extension to the model by introducing a numerical approximation of the classical fracture mechanics theory.
