Abstract: | This study undertakes to predict the deformation behavior of conventionally interlock knitted fabric using a novel geometrical model. Deformation behavior of this kind of knitted fabrics was numerically simulated in course, wale, and bias directions, using FEM method. In order to elaborate the study, high and medium tightness interlock knitted fabrics were selected and deformation of fabrics analyzed in course, wales and bias directions (0°, 45°, and 90°). Accuracy of the proposed geometrical model was investigated comparing the simulated tensile stress–strain curve to the measured one. Output data revealed that the stress–strain curve obtained from simulating method has high conformity with the experimental one. |
