WELFEP: A round robin for weakest-link finite element postprocessors

Abstract A numerical round robin for finite element postprocessors for weakest-link failure probability predictions has been analysed. Three selected problems were analysed by the participants using a number of different postprocessors. In general, good agreement was obtained for the predicted mean nominal failure stress. The predicted values for the failure probability show much more scatter due to the sensitivity of this quantity to integration errors.
