Pipes and pipebends with deforming cross-sections: elbow elements

Elbow elements:

  • are intended to provide accurate modeling of the nonlinear response of initially circular pipes and pipebends when distortion of the cross-section by ovalization and warping dominates the behavior;

  • appear as beams but are shells with quite complex deformation patterns allowed;

  • use plane stress theory to model the deformation through the pipe wall; and

  • cannot provide nodal values of stress, strain, and other constitutive results.
