Mapdl.bsax(val1='', val2='', t='', **kwargs)

Specifies the axial strain and axial force relationship for beam

APDL Command: BSAX sections.

  • val1 – Axial strain component (ε).

  • val2 – Axial force component (N).

  • t – Temperature.


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

The BSAX command, one of several nonlinear general beam section commands, specifies the relationship of axial strain and axial force 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 BSM1, BSM2, BSTQ, BSS1, BSS2, BSMD, and BSTE.
