A plate of width w has a hole of diameter d in the center. A
force F is applied as shown in Figure 11.41. The hole creates a stress
concentration factor (K), which is a function of geometry (d/w) and loading
condition. A quarter model of the plate (as shown) can be used to approximate
the stress concentration factor. Find a table of stress concentration factors
and select a ratio of d/w to conduct a finite element analysis. Define
appropriate boundary conditions for the model, select an appropriate finite
element (and finite element code), define several (at least three) mesh
refinements, and observe the difference in stress concentration approximations
based on the meshes selected.
