dc.description.abstract-translatedThis study presents a 3D finite element model for fracture mechanics-based lifetime estimation of buried polymer pipes. Failure is governed by slow crack growth (SCG), which is modelled using linear-elastic fracture mechanics. The model incorporates an angular-dependent external pressure derived from the ATV DVWK A127 standard. Crack propagation is simulated from an initial defect to its final size with a semi-elliptical crack shape. Stress intensity factor along the crack front is evaluated and used for lifetime estimation. Model validation at the stress–strain level shows good agreement with the ATV design standard, supporting the applicability of the proposed approach.en
