NONLINEAR COMPRESSIVE FAILURE ANALYSIS OF BIAXIALLY LOADED FIBER REINFORCED MATERIALS
Fabrizio Greco, Andrea Pranno, Medaglia Carlo Maria, Lorenzo Leonetti, Rosa Penna - The compressive failure behavior of defected periodic fiber-reinforced composites subjected to macroscopic biaxial loadings is here analyzed from both the theoretical and numerical point of view. The coupled effects of local fiber buckling and matrix or fiber/matrix interface microcracks under unilateral self-contact are included in the analysis by adopting an original full finite deformation approach.
