|Due to increase of the long term application of the polymer materials process of slow stable crack growth became important scientific topic. Therefore, the general goal of the project lies in the accurate description of the slow crack propagation in the case of polymeric structure under complex loading conditions taking into account residual stresses. Slow crack growth can be described by the corresponding fracture mechanics parameters and plays an important part in estimation of this life time. The correlation between experimental data and numerical model is presented. The results enable to estimate effect of the residual stresses, change of material properties or material nonhomogenity on the residual lifetime of the polymeric structures.
