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

Specifies preintegrated membrane thermal effects for shell sections.

Mechanical APDL Command: SSMT

Parameters:

mt11str

Membrane thermal effects component [ M ^T ].

mt22str

Membrane thermal effects component [ M ^T ].

mt12str

Membrane thermal effects component [ M ^T ].

tstr

Temperature.

Notes

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

\[equation not available\]

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

The [ M ^T ] 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 [ M ^T ] and [ B ^T ] quantities (by issuing the ssmt and ssbt commands, respectively).

Unspecified values default to zero.

Related commands are sspa, sspb, sspd, sspe, ssbt, and sspm.
