Definitions

Field Contents SI Unit Example
PID Property identification number of the associated PBEAM and PBEAML. 1

No default (Integer > 0)

  
I Small strain formulation flag.
1
Small strain from time =0 If the small strain option is activated (I = 1), the strain and stress are engineering strain and stress; otherwise they are true strain and stress.
2 (Default)
Full geometric non-linearity.

(Integer)

  
I Shear in beam formulation flag.
ON (Default)
OFF
  
DM Beam membrane damping.

Default = 0.0 (Real ≥ 0.0)

  
DB Beam bending damping.

Default = 0.01 (Real ≥ 0.0)

  

Comments

  1. The property identification number must be that of an existing PBEAM Bulk Data Entry. Only one PBEAMX property extension can be associated with a particular PBEAM.
  2. PBEAMX is only applied in geometric nonlinear analysis subcases which are defined by ANALYSIS = EXPDYN. It is ignored for all other subcases.
  3. This card is represented as an extension to a PSOLID property in HyperMesh.
