1. The problem exhibits symmetry about the midplane of the plate, and about the X and Y axes. This symmetry allows for a 1/8 symmetry sector to be modeled. 2. The approximate analytical solution neglects shear deflection. Shear deflection is accounted for in the
finite element solutions. 3. The target solution is obtained from a fine mesh solution using SOLID95. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 2–7 Benchmark C1
4. The 8-node isoparametric shell (SHELL93), subjected to the same loading, has results in line with the
target solution. The SHELL93 element takes into account shear deflection effects. 5. Deflection and bending stresses converge quickly to the target solution at the center of the plate (target
points 1 and 3) for the solid element test cases. 6. Bending-stresses are maximum at the built-in edges, peaking at the mids...
