Description in English The aim of this work was to develop an easy applicable algorithm of numerical model creation simulating a cracked polymeric pipe under various combination of loading. Proposed algorithm is able to find a real crack front shape using iterative procedure. The main aim was to study the effect of the point load and its consequences on the crack front shape. It was numerically confirmed that point loading causes grater crack extension in axial direction than in the case of pipe loaded by pure inner pressure. This results leads to higher stress intensity factor and lower residual life-time of the pipe system.
