Abstract

Abstract: In order to improve the accuracy of the numerical analysis for the tearing mechanical response of fabric composites, a nonlinear damage constitutive model for PVDF-coated fabric was developed based on the continuous damage mechanics theory. The accuracy of the nonlinear constitutive model is verified by combining the off-axis tensile test with a gradient of 15°. The nonlinear constitutive model was added to the numerical analysis. The results were compared with the conventional folding line model and the trapezoidal tearing test with a gradient of 15° to verify the accuracy of the nonlinear constitutive model in terms of tearing mechanical response. The results show that the nonlinear constitutive model can effectively track the actual stress-strain curve of the fabric. In terms of tearing mechanical response, both models can reflect the effect of series parameter changes on tearing performance and the corresponding tearing mechanism.But the numerical results of the nonlinear constitutive model have a better representation of the complex stresses of tensile-shear coupling during the tearing process.

Key words: warp-knitted fabric, nonlinearity, trapezoidal tearing, tearing strength, off-axis angles, composites
