Abstract

The article presents the results of simulation modeling of the stress-intensity factor depending on the phase composition and the geometric and elastic characteristics of a fibrous polymer composite material. To carry out the modeling using the C++ language, a program was developed that allowed visualizing the calculation results. Using the example of basalt plastics manufactured using the pressure impregnation technology, the values of the stress-intensity factor were determined before and after prolonged exposure to distilled and sea water, alkali solutions, UV irradiation, and thermal cycling.
