  • Numerical simulation of the progressive damage to FRC panels due to shock loading = Numerični model naraščajoče poškodbe FRC-panelov pri udarni obremenitvi
    Zemčík, Robert ; Laš, Vladislav
    This work focuses on the numerical simulation of failure of composite structures. In the previous study we have developed a computational model for the prediction of the critical state of a structure ... made of fiber-reinforced composite (FRC) panels and capable of quasi-static simulation of the subsequent process of local material damage also known as progressive failure analysis (PFA). In this paper, we have extended this model so that the simulation is now a fully dynamic process and therefore the phenomenon of stress wave propagation occurs in the structure. Also, the static Puck's failure criterion used previously has been modified to achieve so-called temporal criterion. The performance of the proposed model is demonstrated on examples of tensile tests of unidirectional single-ply FRC panel with circular hole.
