Applying Constraints

Define two segments to apply constraints on the beam at the wall. Constrain the web in all directions, and the flanges in the normal direction only.

Stress analyses require the solid part to be fully constrained to prevent rigid body motions. Constraining the part so as to prevent any potential motion is essential for obtaining a numerical solution for displacements and stress throughout the structure.

When analyzing the computed stress distribution, examine the stress away from areas that are constrained in all degrees of freedom, as results in these areas may not give an accurate representation of the physical problem.

Constraining the beam wall end in all degrees of freedom would result in high stress concentrations at the flanges, that deviate from the maximum stress predicted by Euler-Bernoulli beam theory. To have a more accurate representation of the stress distribution at the flanges, constrain the web in all degrees of freedom, and the flanges in the axial direction only.

Create a surface segment and rename it to Web Constraint.

Edit the Web Constraint segment node and set the following properties:


Property	Setting
Surfaces	wall side - web
Type	Constraint

The constraining method is defined through the Solid Stress Constraints physics condition for the segment. The default method is Fixed, which is appropriate to this case, as it constrains the web in all directions.

Create a surface segment and rename it to Flanges Constraint.

Edit the Flanges Constraint segment node and set the following properties:


Property	Setting
Surfaces	wall side - lower flange
Surfaces	wall side - upper flange
Type	Constraint

Specify a zero normal displacement constraint for this segment, to prevent movement normal to the plane of the flanges:

Select the Flanges Constraint > Physics Conditions > Solid Stress Constraints node and set Method to Normal Displacement.
By default, the Normal Displacement value is set to zero.
The part is now fully constrained.
Save the simulation.
