摘要：

We present an analysis of the stresses induced inside woven composite microstructures, using the technique of homogenizing periodic media, with stresses prescribed. Thus, by double homogenization, we have considered the microscopic stress field inside the woven failure as well as inside the yarn which constitutes a unidirectional fiber resin composite. To help in our interpretation of the results, we computed a few scalars microstress field, these reveal the overstresses inside the different constituants and the risks of delamination at the yarns matrix interface.
