Specifies a preintegrated bending stiffness for shell sections.
Bending stiffness component (symmetric lower part of submatrix
The behavior of shell elements is governed by the generalized-stress/generalized-strain relationship of the form:
The SSPD command, one of several preintegrated shell section commands
specifies the bending stiffness quantity (submatrix [
data) for a preintegrated shell section. The section data defined is associated
with the section most recently defined (via the SECTYPE command).
Unspecified commands default to zero.
