SSPE
SSPE, E11
, E21
, E22
, T
Specifies a preintegrated transverse shear stiffness for shell
sections.
-
E11,E21,E22 Transverse shear stiffness component (symmetric lower part of submatrix [
E]).-
T Temperature.
Notes
The behavior of shell elements is governed by the generalized-stress/generalized-strain relationship of the form:
The SSPE command, one of several preintegrated shell section commands, specifies
the transverse shear stiffness quantity (submatrix [
E
]
data) 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 SSPA, SSPB, SSPD, SSMT, SSBT, and SSPM.
If you are using the SHELL181 or SHELL281 element's Membrane option (KEYOPT(1) = 1), it is not necessary to issue this command.
