摘要

Woven fabrics service in technical textile applications are invariably exposed to many deformation modes, in particular tensile and puncture loadings. During its use, woven fabrics might be exposed to the puncture effect of sharp objects in perpendicular direction to that of in-plane tension. With extreme engineering requirement, technical woven fabrics are expected to provide resistance against puncture impact damage, which lead to tearing and structural failure. The paper will discuss on experimental and puncture simulation model analysis of plain woven fabric. The development of yarn geometry and woven fabric assembly were established within ABAQUS pre-processor finite element software package. Four different impactor shapes specifications were employed in the research. With finite element procedures, meso-model of large plain woven fabric model comprising of 112 warp and weft yarns was established. Stress-strain analysis and damage evolution analysis were explored on the simulated models.
