Abstract
This paper introduces a new methodology from which better material parameters may be identified. The method will account for both non‐repeatability of test data (by means of signal‐to‐noise weighting factors) and potential discrepancies between material parameters in different deformation modes (by means of a multi‐objective optimization process). Finally, to show the application of the method, test data for a 2×2 twill weave fabric from different modes (namely, uniaxial extension and bias‐extension) are selected to identify the model parameters of an orthotropic material model. The procedure may be applied to other material models and applications.
