'Cantilever Beam Mesh Order Comparison' simulation project by rszoeke


#1

I created a new simulation project called 'Cantilever Beam Mesh Order Comparison':

Simple Cantilever Beam Static Analysis. Showing the difference of using a 2nd order mesh over a 1st order one.


More of my public projects can be found here.


#2

Quick comparison of mesh order influence on a simple cantilever beam in bending.

Displacement comparison - Left: 1st order, Right: 2nd order

Equivalent Stress (von Mises) comparison - Left: 1st order, Right: 2nd order

As one can see, due to shear locking the 1st order mesh greatly underestimates the deformations and stresses.
