Select Equivalent Stress in the Outline to review the von-Mises stress distribu-
tion. The following figure shows that the maximum von Mises stress is located
at the two entrant corners on the right side of the wrench with a magnitude
of 159.77 MPa, which is below 207 MPa, the yield strength of Stainless Steel.
Decrease the element size in the Details of “Body Sizing” and solve again to
see if any increase in the solution accuracy.

Modeling tips: ANSYS Workbench can work with native geometric models cre-
ated in other CAD systems such as SolidWorks, CATIA and Pro/E. It also allows
geometry to be imported in neutral file formats such as IGES, Parasolid and SAT.
To import a Parasolid file of a planar geometry for example, you may right-click
on the Geometry cell. Choose Import Geometry and Browse to select the
Parasolid geometry file. Right-click on the Geometry cell, and select Properties
in the context menu. For plane stress models, make sure that the Analysis Type
is changed to 2D in the Properties of Schematic A3: Geometry window.
