Numerical Simulation and Experiment Verified for Transverse Tensile Properties of Weft-Knitted Fabric

The modeling software SolidWorks was applied to build a model of the weft-knitted fabric to measure the geometric dimension of the weft-knitted loop. Meanwhile, the multi-physics coupling software COMSOL Multiphysics was used to perform simulation analysis of the loop deformation and stress distribution in the transverse tensile strength of the weft-knitted fabric with directional displacement. And a fabric transverse tensile strength testing experiment was conducted to verify the feasibility of the numerical simulation. The geometric model and numerical simulation analysis model built in this paper were used to simulate the transverse tensile performance of the fabric. The loop deformation measured by numerical simulation is consistent with the experimentally measured loop deformation, and the rate of error between the stress-strain numerical analysis results and the experimental results falls within 9.2%, indicating a good feasibility of the numerical simulation.
