【 摘 要 】

In this work, a numerical model for predicting the residual life of structures made of polymer composite materials using a structural-phenomenological model is proposed. To estimate the residual life of PCM structures under cyclic loading, it is proposed to use the approach of explicit describing the process of adhesive layers' destruction. The model is implemented in the APDL language in ANSYS Mechanical engineering complex. The model and the program testing was carried out on a flange type construction with a defect. A comparison of numerical experiments was made for flanges with and without the defect.
