Sometimes, it may be required to update set lists to reflect changes in the model. This is especially true for sets created by the Locate method, in which the pick coordinates and box tolerance will determine which objects will be added to the set.

What are the 3D Bearing Load Requirements?

Categories: Model Inputs

Bearing loads are defined as sinusoidal traction distributions applied to cylindrical surfaces as force vectors (Fx and Fy), or as a force magnitude (F) and angle (α). Bearing loads are defined in the Load tab via Select > Any Surface/Face/Face Surface > Bearing.

Categories: Global-Local Analysis, Model Inputs

In StressCheck, there are two TLAP-Traction options for applying one or more Total Loads at a Point (TLAPs) on selected element faces or geometric surfaces to generate a statically equivalent set of tractions: Near Faces and All Faces.
