4.15.1.8. MultiaxialCyclicPlasticityΒΆ

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
