The effect of residual stresses on crack shape in polymer pipes
Original language description
The effect of residual stresses on crack geometry and consequently on crack behaviour in polymer pipes is estimated. Crack geometry has a significant influence on the resulting stress intensity factor value. The shape of a crack in three-dimensional analysis was numerically estimated using a special routine which ensures constant stress intensity factor along the crack front. It was found that the crack shape was influenced by the presence of residual stresses and significant increase of the stress intensity factor for a pipe with residual stresses in comparison with a pipe without residual stresses was observed. An approximative equation for stress intensity factor estimation in a pipe with residual stresses was presented and its accuracy tested.
