Specifies the cross section twist and torque relationship for beam
APDL Command: BSTQ sections.
Twist component (χ).
Torque component (τ).
The behavior of beam elements is governed by the generalized- stress/generalized-strain relationship of the form:
The BSTQ command, one of several nonlinear general beam section commands, specifies the cross section twist and torque relationship for a beam 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 BSAX, BSM1, BSM2, BSS1, BSS2, BSMD, and BSTE.
