Implementation and calibration of meso-scale modeling technique for simulation of tensile behavior of fabric materials

Present paper investigates the simulation of quasi-static response of fabric materials subjected to uniaxial tensile loading. The purpose of this research is to simulate the fabrics mechanical behavior accurately determining the quasi-static elastic and failure properties of fabric yarn and to rank, from the analysis point of view, the parameters which influence the fabric behavior. In particular, a meso-scale approach was employed to model the behavior of different para-aramid fabrics using LS-DYNA software whereas the Nelder & Mead Simplex optimization algorithm was implemented for the determination of material model's parameters by the fitting of numerical and experimental tensile loading curve.
