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)


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
