4.15.1.8. BoundingCamClayΒΆ

nDMaterial('BoundingCamClay', matTag, massDensity, C, bulkMod, OCR, mu_o, alpha, lambda, h, m)

This command is used to construct a multi-dimensional bounding surface Cam Clay material object after Borja et al. (2001).

matTag (int)

integer tag identifying material

massDensity (float)

mass density

C (float)

ellipsoidal axis ratio (defines shape of ellipsoidal loading/bounding surfaces)

bulkMod (float)

initial bulk modulus

OCR (float)

overconsolidation ratio

mu_o (float)

initial shear modulus

alpha (float)

pressure-dependency parameter for modulii (greater than or equal to zero)

lambda (float)

soil compressibility index for virgin loading

h (float)

hardening parameter for plastic response inside of bounding surface (if h = 0, no hardening)

m (float)

hardening parameter (exponent) for plastic response inside of bounding surface (if m = 0, only linear hardening)

The material formulations for the BoundingCamClay object are:

  • 'ThreeDimensional'

  • 'PlaneStrain'
