FEMに基づいた織物構造のせん断変形挙動の高精度評価

Braided structures which consist of warp and weft yarns has been used in many structural applications. Over the decades, the deformation behaviour of braided structure has been studied by many researchers. However, in most cases, the effect of slippage of yarns has been neglected, so their predictions overestimate the actual response. Although the existing studies considering slippage of yarns, there are some limitations for the movements of yarns. The main purpose of our study is to propose an estimation equation for the deformation and frictional response of braided structure based on FEM analysis. In particular, the effects of yarn’s geometries and material properties on the response have been investigated systematically.
