ABAQUS Keywords Reference Manual  

*EOS COMPACTION
Specify plastic compaction behavior for an equation of state model.

This option is used to specify plastic compaction behavior for a hydrodynamic material. It must be used in conjunction with the *EOS, TYPE=USUP option.

Product: ABAQUS/Explicit  

Type: Model data

Level: Model  

References:
There are no parameters associated with this option.

Data line to define the P – α compaction behavior: 

First (and only) line:

  1. Reference sound speed in the porous material, . (Units of LT–1.)

  2. Value of the porosity of the unloaded (virgin) material, . (Dimensionless.)

  3. Pressure required to initialize plastic behavior, . (Units of FL–2.)

  4. Compaction pressure at which all pores are crushed, . (Units of FL–2.)
