Abstract
A finite element analysis of 3D stitched textiles in the mesoscale, under compression loading by using Catia V5R21 and Abaqus 2021 software was carried out. The model was validated by the experimental results. The interior geometry of the fabric was created using the experimental geometry measurements based on the textile fiber microscopic images. The 3D repetitive fabric unit cell was simulated using the periodic boundary conditions. The loading curves and deformation of the textile fabric were investigated based on the preform behavior under compression loading and compared with the experimental results. It was observed that increasing the compressive force increased the fiber volume fraction. The fiber volume fraction is 51.6% for the practical sample subjected to a compressive force of 5 KN and 52.6% for the modelled sample due to the application of a force of 7 KN. The simulated and experimental values of maximum stress were 2.99 and 2.5 MPa, respectively, at the strain rate of 47.5 and 47%, respectively. The simulation and the experimental analysis exhibited almost identical behaviors under equal compression stress.
