In this paper some experimental results of a bullet impact on composite armor are discussed together with numerical modeling approaches. The development of high-quality composite sandwiches for ballistic protection is the target of a grant project in terms of which the research is being conducted. Traditionally, a vehicle ballistic protection is mainly achieved using metal-based armor which is heavy...
Results of FEM simulations of fatigue crack growth under mixed mode loading are presented in this paper. At Czech Technical University in Prague (CTU) the program code which uses commercial software ABAQUS for fatigue crack simulations has been developed. The program works on basis of gradual crack extending. In simulation are considered small scale yielding conditions. Both classic criteria (J-integral,...
