('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
