Originální abstrakt

Accelerated tests of the polyethylene pipes are necessary for the pipe lifetime calculations. Accepted methodology for prediction of slow crack grow rate in these materials is fatigue testing of CRB (cracked round bar) specimens. This paper deals with the FEM modelling of the crack propagation during the CRB test under the influence of residual stresses. The crack growth is described based on the stress intensity factor and Paris-Erdogan law. The purpose of this research is to determine, if the residual stress influences crack behavior during CRB test.
