Reply To: Why is deflection for fatigue life not at point of loading?

Don't apply line contact to solid elements.  Stress is force/area.  A line has zero area, therefore the stress is infinity.

Create a two cylinder bodies to make frictional contact with the RCC beam. Use a small element size under the point of contact. This will allow many element faces on the RCC to make contact with the cylinder and create a finite area so the force applied by the cylinder will create a finite stress.
