Materials for ballistic protection are developed with a life-saving purpose and have resistive ability to withstand impacts without damaging the body they are protecting. The development of new materials involves the analysis of deformations occurring after impact. Traditional processes, which use plasticine, strain gages, extensometers, linear variable differential transducers to carry out the measurements, are laborious and inefficient. Few institutions in the world have the ability to develop new ballistic materials. In Brazil, the Aeronautics and Space Institute (IAE), develops new materials using the traditional process through plasticine. Thus, the development of a solution to determine the deformations and their characterizations (diameter, height), can increase the efficiency of this type of test. In this work, the steps for the development of an application that uses image processing techniques to determine the diameter of the deformations are shown. The experiments performed and the results obtained are also shown. |
