F = 7,539.82 lb Analysis Assumptions and Modeling Notes
The stiffness matrix formed in the first load step is automatically reused in the second load step. A new stiffness
matrix is automatically formed in the third load step because of changed boundary constraints. The mesh
density is biased near the centerline and outer edge to recover stress values near those points.

Case 3 1. Theoretical σmax occurs at a node location; ANSYS results, taken from element solution printout, are at
the centroid of the nearest element. 2. This result is at the edge of the plate since point loading causes (theoretically) infinite stresses at the
point of load application. Figure 15.2 Displa...
