ansys.mapdl.core.Mapdl.tbeo#

Mapdl.tbeo(par='', value='', **kwargs)#

Sets special options or parameters for material data tables.

Mechanical APDL Command: TBEO

Parameters:
parstr

Parameter name:

  • CAPCREEPREG - Available for the viscoplasticity/creep model ( tb, CREEP ), allows two creep models to be specified via the same material ID when used with the Extended Drucker-Prager model ( tb, EDP ).

  • FDCS - Coordinate system to use with location (XCOR, YCOR, ZCOR) or displacement (UX, UY, UZ) field variables.

  • NEGSLOPE - Controls whether negative tangent slopes of the stress-strain curve are allowed for multilinear kinematic or isotropic hardening in a rate-independent plasticity analysis.

valuestr

Parameter value:

When Par = CAPCREEPREG –

  • SHEA - Use the shear stress-state creep model with the Extended Drucker-Prager model.

  • COMP - Use the compaction stress-state creep model with the Extended Drucker-Prager model.

When Par = FDCS –

  • Any predefined, user-defined, or custom ( local or cs ) Cartesian coordinate system number.

When Par = NEGSLOPE –

  • 0 - Error-trap negative tangent slopes of the stress-strain curve (default).

  • 1 - Allow negative tangent slopes of the stress-strain curve.

Notes

Issue the tbeo command after activating the material data table ( tb ) but before defining data for the table ( tbdata ) or a point on a nonlinear data curve ( tbpt ).

If the defined material data table has subtables, issue the tbeo command for each desired subtable.
