The evolution of damage in a woven composite results from the interaction and competition among several elementary mechanisms which are greatly influenced by the microstructure. Thus, in order to develop a model as close as possible to the physics, it is necessary to observe, understand and describe each mechanism on the most appropriate scale. In this work, the construction of a woven composite micro model is presented as well as an homogenization procedure to study microcracking kinetics on the microscale and its impact on the mesoscale.
