Damage prediction of composite pipes
Original language description
This article is focused to the estimation of the residual lifetime of the multilayer polymer pipes. The main task is to asses differences in propagation of the creep crack in the multilayer (composite) pipe line in the comparison with conventional homogenous pipe. To predict residual lifetime of a multilayer pressured pipe, the stress intensity factors during the creep crack propagation has to be estimated. From the results it is visible that dangerous situation is, when crack penetrated interface between inner protective layer and main pipe, because softer outer protective layer changes stress state in front of the crack tip and significantly decrease residual lifetime of the structure
