StressCheck Tutorial: TLAP-Traction vs Uniform Traction Case Study
Abstract: TLAP-Traction enables tabular point forces and/or moments (i.e. TLAPs) to be applied to solid element faces as statically equivalent, but generally non-uniform, traction distributions. This loading method is especially useful for Global-Local workflows.
For a case study of a plate with hole, with the hole located an edge distance ED from the surface of load application, the maximum 1st principal stress in the hole was assessed for TLAP-Traction: Near Faces, TLAP-Traction: All Faces and constant Traction methods. All traction distributions resulted in a total axial force of 16 lbf. The goal is to determine the minimum ED for which Saint-Venant’s Principle is true.
