Numerical Results

The following video shows how to plot the deformed shape and use it to check if the displacement constraints have been applied correctly.  We next take a look at

$\sigma_x$

 variation in the model. 

We interrogate 

$\sigma_x$

 variation in the interior of the model using a plane.

Verification and Validation

• Check that the solution agrees with the mathematical model

  • Are the boundary conditions on displacement and traction satisfied?

  • Is equilibrium satisfied?

    • Do the reaction forces balance the applied load?

• Check that the numerical error is acceptable

  • Are the ANSYS results reasonably independent of the mesh?

    • We can refine the mesh by reducing the Size Controls and updating the solution.  We can then compare the results to the original mesh. 

• Compare with hand calculations for the bending stress and maximum displacement
