Weld Surface Strengths

The strength reduction factor, whether calculated automatically or user-specified, is applied as a simple multiplier to scale the strength of the material. In particular, we scale the maximum effective stress, σeff,max, of the material.

Where η is the strength reduction factor and must lie in the range 0 < η ≤ 1. This scaling of the maximum effective stress causes the material that lies on the weld surface to fail sooner than the same material that is not on the weld surface.

The strength reduction factors can be visualized in the Ansys output results with SVAR12.
