Modeling of Nonlinear Behavior of Textile Composites
S. Urbanová, J. Vorel, M. Šejnoha
pages 332 - 333, full text

This paper deals with the analysis of composite systems reinforced by plain weave textile fabric with attention accorded to the modeling of damage. Solution of this problem requires complex and time demanding preparation consisting of several steps such as formulation of the periodic unit cell exploiting computational microtomography to determine the actual 3D porous structure, meshing the computational model equipped with appropriate boundary conditions and finally evaluating the effective properties of yarns using, e.g. the Mori-Tanaka micromechanical model. Assessing the damage evolution of such systems then requires the solution of the first-order homogenization problem of a periodic unit cell assuming non-liner response of individual phases. Herein an approach based on Hashin-type failure criteria combined with an appropriate damage evolution law is examined.
