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'
