Application of the Inverse Analysis for Determining the Material Properties of the Woven Fabrics for Macroscopic Approach
The current paper intends to realise a fast method for determining the material characteristics in the case of composite materials used in the airbags manufacturing.For determining the material data needed for other complex numerical simulations at macroscopic level there was used the inverse analysis method.In fact,there were carried out tensile tests for the composite material extracted along two directions-the direction of the weft and the direction of the warp and afterwards there were realised numerical simulations (using the Ls-Dyna software).A second stage consisted in the numerical simulation through the finite element method and the experimental testing for the Bias test.The material characteristics of the composite fabric material were then obtained by applying a multicriterial analysis using the Ls-Opt software,for which there was imposed a decrease of the mismatch between the force-displacement curves obtained numerically and experimentally,respectively,for both directions (weft and warp) as well as the decrease of the mismatch between the strain-extension curves for two points at the Bias test.
