Mapdl.ssmt(mt11='', mt22='', mt12='', t='', **kwargs)

Specifies preintegrated membrane thermal effects for shell sections.

APDL Command: SSMT

mt11, mt22, mt12

Membrane thermal effects component [MT].




The behavior of shell elements is governed by the generalized- stress/generalized-strain relationship of the form:

The SSMT command, one of several preintegrated shell section commands, specifies the membrane thermal effects quantity (submatrix [MT] data) for a preintegrated shell section. The section data defined is associated with the section most recently defined (via the SECTYPE command).

The [MT] quantity represents membrane stress resultants caused by a unit raise in temperature on a fully constrained model. For a layered composite shell, it is usually necessary to specify both the [MT] and [BT] quantities (by issuing the SSMT and SSBT commands, respectively).

Unspecified values default to zero.

Related commands are SSPA, SSPB, SSPD, SSPE, SSBT, and SSPM.
