Abstract:

In order to predict the tensile properties of fabrics, numerical simulations of fabric tensile were studied by using finite element method, and corresponding experiment verification was presented. Firstly, the geometry parameters of the yarns were obtained by observing the morphology of the fabrics with the help of super depth of field digital microscope VHX-5000. Then, the mechanical unit-cell models of the three-elementary weave were built by AutoCAD. Then, based on the experiment of yarn tensile and the periodic boundary conditions, the tensile properties of the three-elementary weave were studied using ANSYS software. Finally, the results of numerical simulations and experiments were compared. The results indicate that the error between the simulated results and the experimental results is about 10%, verifying that numerical simulation using the finite element method is effective.
