A solid-beam approach for mesoscopic analysis of textile reinforcements forming simulation

Abstract. Draping and forming of textile reinforcements are usually performed thanks to finite element models with continuous media assumption. The specific purpose of mesoscale model is to faithfully reproduces defects like yarn buckling or gapping during the process. Such defects are crucial outputs because they have huge impacts on mechanical and permeability properties of the whole textile. However, mesoscopic analysis usually leads to expensive computation cost and needs to be optimized to propose a cost-effective response to this problem. Thus, this document aims to develop a solid-beam approach for mesoscale model, with coarse geometric assumption but with finite element and constitutive law formulation taking into account the fibrous aspect of the fabric.
