Abstract
The knowledge of the characteristics and behavior of the composite material is of great importance, bearing in mind of its wide application besides serving as a parameter for identification of possible problems caused by material degradation, avoiding that greater damages could irreversibly damage the composite. In this way, the present work makes an analysis of the mechanisms of failure of the polymeric composite PMMA (polymethylmethacrylate) reinforced with fiberglass. And, using experimental data obtained in the laboratory and simulating the behavior of the material in the software Abaqus through the implementation of the tool XFEM (Xtended Finite Elements Mode) in Loading Mode I, which analyzes fissures generated by fields of discontinuities without the need to constantly update the mesh, allowing to observe the critical stresses acting on the fiber/matrix interface.
