TI - A new modelling approach based on Binary Model and X-FEM to investigate the mechanical behaviour of textile reinforced composites T2 - Computer Modeling in Engineering \& Sciences PY - 2009 VL - 42 IS - 1 SN - 1526-1506 AB - The purpose of this paper is the presentation of a new efficient modelling strategy based on the combination of Binary Model and Extended Finite Element Method (X-FEM). It is applied to represent the internal architecture of textile reinforced composites where the resin-saturated fabric is characterised by a complex geometry. Homogenisation methods are used to compute the effective elastic material properties. Thereby, the discrete formulation of periodic boundary conditions is adapted regarding additional degrees of freedom used by finite elements which are based on the X-FEM. Finally, the results in terms of effective material properties reveal a good agreement with parameters obtained by experimental tests.
