However, the complex response of composite materials coupled with high costs and limited amount of data from ballistic testing has lead to modeling and simulation of ballistic body armor with different grade of material becomes the best option to optimize and design the composite body armor with less weight and affordable cost. The long term goal of this research is to develop domestic knowledge, model and simulate capability of composite armors with less cost and weight. As a research methodology there was modeling and simulation by Solid work 2012 and Abaqus 6.10software were used to model and simulate the composite bullet resistant body armor respectively.
