This is supposed to be a very classic analytical solution in applied elasticity. Forgive me if this is a repost or some correction has been made before. I had a hard time with it.
Problem statement: uniform pressure is applied on cirular area (radius=r) on top of a semi-infinite plane. Find the vertical deflection.
We got discrepancy between FEA solution and analytical solution which I found from different textbooks (famous and non-famous): Deflection within the circle is good, however, no good outside the circle.
We found the correct solution is attached.
