Abstract
The present paper deals with the multi-scale modelling and finite element analysis of Kevlar/Epoxy 3D Orthogonal woven composite (3DOWC) subjected to ballistic impact by a conical-cylindrical steel projectile. These are designed by utilising a Micro-Meso-Macro transition approach called Macro Homogeneous-Meso heterogeneous modelling technique. The Micro-Meso-Macro transition approach has been implemented in this research to develop the complex weave architecture of the target plate, and, a voxel-based non-conformal mesh has been used to understand the behaviour of Representative Volume Element (RVE). The model is validated by using 2D weave architecture which has been analysed for conical 90 ° projectile made up of 7.62 calibre. The damage properties are implemented using a user-defined function in the explicit analysis VUMAT. The Macro homogeneous results provide the velocity variation and energy absorption of the projectile with respect to the time history. Also, the energy absorption by its constituents are presented here, and substantial validation of results have been observed with the available literature.
