Abstract
Many composites consist of a fabric structure embedded in a matrix material. The fibres are often made of material which shows noticeable plastic deformation. The overall stiffness of the specimens is usually determined by the stiffness of these fibres, such that the correct modeling of the orthotropy of the composite is very important. In addition, the structure experiences large deformations which must be accounted for. In the present paper, suitable models for this type of materials are therefore derived in the framework of finite anisotropic plasticity. A main problem is, however, the lack of experimental data in the literature. For this reason, a computer model of the composite is set up for numerical experiments. The results serve to determine the material parameters of the developed continuum mechanical model.
