- nDMaterial('MultiaxialCyclicPlasticity', matTag, rho, K, G, Su, Ho, h, m, beta, KCoeff)
This command is used to construct an multiaxial Cyclic Plasticity model for clays
matTag
(int)integer tag identifying material
rho
(float)density
K
(float)buck modulus
G
(float)maximum (small strain) shear modulus
Su
(float)undrained shear strength, size of bounding surface \(R=\sqrt{8/3}*Su\)
Ho
(float)linear kinematic hardening modulus of bounding surface
h
(float)hardening parameter
m
(float)hardening parameter
beta
(float)integration parameter, usually beta=0.5
KCoeff
(float)coefficient of earth pressure, K0
