Applying Material Properties and Contact Sets

You define the material properties and contact sets.

1. In the Simulation study tree, right-click the bolted connection study folder and select Properties.
2. In the Nonlinear-Static dialog box, under Geometry nonlinearity options, select Large strain option.

   You select the Large strain option to model plasticity in the bolted connection.

3. Under Solver, select Direct Sparse and click OK.
4. Right-click Parts and select Apply Material to All .
5. In the Material dialog box, for Model Type, select Plasticity- von Mises.
6. Click Apply and Close.

   The elastic-plastic material properties of Alloy Steel are assigned to the bolt and the nut.

7. Right-click Connections and select Contact Set . In the PropertyManager, do the following:
   1. For Faces, Edges, Vertices for Set 1 , select the 2D body of the bolt.

      

   2. For Faces for Set 2 , select the 2D body of the nut.

      

   3. Under Advanced, select Surface to surface.
8. Click .

   No penetration contact without friction is applied between the touching thread regions of the bolt and the nut.
