Solution Comparison
The theoretical solution for this problem is:
Inside surface of cylinder: SX = -1,000 psi, SZ = 1,520.8 psi
Outside surface of cylinder: SX = 0 psi, SZ = 520.8 psi.
In the ANSYS solution shown, the upper arrow shows Sx normal to
the y-z plane, which corresponds to the cylinder hoop stress. The scale
at the bottom indicates a maximum value of 1,528 psi, which is close to
the theoretical value of 1,521 psi.
The lower arrow shows Sx in a direction normal to the inner surface
of the cylinder with a scale value of -1,006, again close to the internal
pressure of 1,000 psi.
Thus the ANSYS-calculated results seem to agree pretty well with the
theoretical results.
