Why is pressure load stiffness in ANSYS 11.0 not being used for this SHELL181 model? SHELL181 is supposed to use pressure load.

You may have applied the prestress as an edge load. In Table 2.9 of the Theory Manual Section 2.15, there is the note below referring to SHELL181: "x[3] = Same as x, but does not apply to edge loading." |
