A person can protect him/her self against a ballistic thread by wearing ballistic protection such as hard plates and soft plates. Brapa developed a software tool to describe the protective performance of such a ballistic plate against projectiles. based on material properties and projectile properties, it is possible to predict whether the plate can protect the wearer against the ballistic threat. These calculations are based on energy calculations of the various processes, which occur during impact.
Below, an example of energy calculations are given of a bullet, hitting a soft plate.
