(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'`` See also for `information `_
