Abstract
Inflatable Aerodynamic Decelerators (IADs) are often constructed from complex fabrics. The simplest example being a plain woven fabric. Optimization of IADs relies heavily on a detailed understanding of the IAD materials. A Mesomechanical material model of a plain woven fabric is implemented in a nonlinear finite element analysis code and presented in this work. The model is developed in MATLAB to facilitate exploration and learning. Derivation of the model is initially presented by Ivanov and Tabiei and utilizes the homogenization methodology; commonly used in composites. Geometric nonlinearity is modeled through the reorientation, as well as, locking of the yarns. The example shows the mesomechanical material model is capable of capturing the dual behavior corresponding to that of actual plain woven fabrics.
