Data line to define the plastic compaction behavior

First (and only) line

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

  2. Value of the porosity of the unloaded (virgin) material, n0 . (Dimensionless.)

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

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