Abstract
The finite element method (FEM) is one of the most widely used and most popular numerical methods for analyzing plate structures. In the last years an increase of interest in a new type of numerical methods known as meshless methods was observed. One of the areas where meshless methods are convenient to use is the analysis of plate and shell structures. The paper deals with application of meshless methods on modelling of inelastic damage using continuum damage mechanics (CDM) of layered plate composite structures reinforced with long unidirectional fibers. For numerical simulations of elastic plastic damage of layered composite plates own computational programs were implemented in MATLAB programming language. For solving a system of nonlinear system equations Newton-Raphson method was used. Evaluation damage during plasticity has been solved using return mapping algorithm. The results of elastic-plastic damage analysis of composite plate with unsymmetrical laminate stacking sequence are presented.
