| Summary: | Carbon fiber reinforced plastics (CFRP) are now being used in primary structures of airplanes, ships, and automotive engineering and for applications that demand sustained high reliability and strength during long-term operations. The present work provides a three-dimensional (3D) model that has been established for the simulation of the multidirectional carbon fiber reinforced plastic (CFRP) composite layer which enables understanding of the mechanical properties at failure using finite element simulation software ANSYS. The matrix is considered isotropic and elastic-plastic. Moreover, the carbon fiber is considered transversely isotropic and linear elastic for the finite element modeling. The maximum stress-strain criterion is used to determine the failure of fiber and matrix of composite layer for both analytical and modeling analysis. The modeling result shows that the elastic modulus in fiber orientation is significantly higher. Numerical and analytical results of nonlinear mechanical stress and the distribution on the multilayer show good agreement with experimental results. |
