摘要：
A 3D finite element model of three-point flexure test of carbon fiber/epoxy composite laminates is developed and analyzed with the finite element software ANSYS. Based on the Hashin criterion, a stiffness degradation method is adopted to predict the progressive failure properties of the carbon fiber/epoxy composite laminates. For carbon fiber/epoxy composite, five failure modes: fiber tensile failure, fiber compressive failure, matrix tensile cracking, matrix compressive cracking and fiber-matrix shear-out failure are included in the present model. The calculated load-displacement curve and the final flexural failure strength are compared with the experimental result, and the finite element results are in good agreement with the experimental values.
