4.5 Case Study with ANSYS Workbench
Problem Description: A combination wrench is a convenient tool that is used to apply
torque to loosen or tighten a fastener. The wrench shown below is made of stainless steel
and has a thickness of 3 mm. Determine the maximum deformation and the distribution
of von Mises stresses under the given distributed load and boundary conditions.

Solution
To solve the problem with ANSYS Workbench, we employ the following steps:

Step 1: Start an ANSYS Workbench Project
Launch ANSYS Workbench and save the blank project as ‘Wrench.wbpj’.
