Description

Using a mesoscopic model is a common and effective approach to predict the physical properties of woven composites. However, the main drawback of the conventional meso-model, which has the continuous mesh, is the difficulty of meshing the matrix, especially near the interfaces with the reinforcement. The model superposing a reinforcement mesh and applying a constraint based coupling is considered to be an effective modeling technique to solve this issue. To assess the capability of the coupling model, we compare the predictive mechanical properties of UD and the plain woven model between the coupling model and conventional model. The results show a good agreement between the two models.
