Benefits: Abaqus/Standard now supports the modeling of thick-walled pipes, in which the hoop and radial stress due to the applied pressure vary across the pipe cross-section. The thick-walled element formulation better predicts the inelastic response under the effect of internal and external applied pressure for larger wall thickness-to-radius ratios. In addition, the bending and torsional behavior is modeled more accurately without recourse to thin-wall assumptions.
