This command is used to construct a multi-dimensional bounding surface Cam Clay material object after Borja et al. (2001).
| nDMaterial BoundingCamClay $matTag $massDensity $C $bulkMod $OCR $mu_o $alpha $lambda $h $m |
| $matTag | integer tag identifying material |
| $massDensity | mass density |
| $C | ellipsoidal axis ratio |
| $bulkMod | initial bulk modulus |
| $OCR | overconsolidation ratio |
| $mu_o | elastic shear modulus |
| $alpha | pressure-dependent parameter |
| $lambda | soil compressibility index for virgin loading |
| $h | hardening parameter |
| $m | hardening parameter |
The material formulations for the BoundingCamClay object are "ThreeDimensional" and "PlaneStrain"
