Good morning all,
I am trying to compare Ansys results to hand calculations for Shear Stress and Maximum Shear Stress for a simple cantilever beam (10mm x 10mm x 100mm) with a 1N load at the end face. I have modeled the solid beam in SpaceClaim as an extrusion of a rectangle so I am not using the predefined beams built in SpaceClaim.
At the fixed support, I ended up using remote displacement to have the option of deformable behavior on because when using the standard fixed support I get singularity points that mess up the results.
The support and the load has been applied to the faces at each end of the solid beam (normal to the longitudinal axis Y)
The hand calculation for the Shear Stress is just the Load/Area and for the Maximum Shear Stress is (3/2)*Load/Area.
I get the Von Mises Stress spot on but for the Shear Stress and Maximum Shear Stress I get odd results. If you could help me understand what is going on it would be very much appreciated.
