11--18

The goal of this paper is to present the numerical results of elastic damage of thin unidirectional fiber-reinforced composite plates. The numerical implementation uses a layered shell finite element based on the Kirchhoff plate theory. Newton-Raphson method is used to solve the system of nonlinear equations and evolution of damage has been solved using return-mapping algorithm. The analysis is performed by finite element method and user own software is created in MATLAB programming language. One problem for two different materials was simulated in order to study the damage of laminated fiber reinforced composite plates.

This paper presents numerical modelling of composite damage by finite element method (FEM). The damage model is implemented it in ANSYS software for a one dimensional bar element. A return mapping algorithm integration is implemented in conjunction with plane stress element PLANE182. These subroutines should be linked with the ANSYS program beforehand.
