This study proposes a continuous approach based on hypoelastic behavior for simulating the forming process of interlock textile composites, which can accurately trace specific material behavior.
Numerical simulation of the textile composites forming plays an important role in improving the manufacturing quality, reducing the manufacturing cycle, and manufacturing cost. The focus is on the shaping of one or several layers of G1151 interlock reinforcement. Based on the continuous approach at the macroscale, an approach using a hypoelastic behavior is proposed considering the specific interlock textile material behavior. The stress accumulation is carried out in frames defined by the direction of the warp and weft yarns. The approach is implemented in the commercial software Abaqus. By adding inter-layer contact properties, this approach can realize the simulation of multi-layers textile composites with different yarn orientation configurations. Experimental analyses have shown that this approach can correctly trace the specific behavior of interlock textile composites.
