Notes
The behavior of shell elements is governed by the generalized-stress/generalized-strain relationship of the form :
\[equation not available\]The sspa command, one of several preintegrated shell section commands, specifies the membrane stiffness quantity (submatrix [ A ]) for a preintegrated shell section. The section data defined is associated with the section most recently defined (via the sectype command).
Unspecified values default to zero.
Related commands are sspb, sspd, sspe, ssmt, ssbt, and sspm.
