Anisotropic Constitutive Model

Numerical implementation of an anisotropic constitutive model for clays (SANICLAY) is presented. Moreover, a case study in which a soil embankment is placed on a K0-consolidated over-consolidated clay is analyzed by conducting an elastoplastic fully-coupled finite element analysis. It is shown that anisotropy has significant impact on the ground settlement caused by the placement of soil embankment and on the pore pressure generation and dissipation within the foundation soil. The simulations using SANICLAY favorably compare with the field measurements of ground settlement and pore pressure. The drawbacks of the use of an isotropic elastoplastic model (Cam Clay) are also demonstrated.

Fully Coupled

A fully-coupled and 3-D model for induction and strain of cubic magnetostrictive materials is presented which incorporates geometry dependent demagnetizing fields, current induced fields, and stress dependent permeability. Maxwell’s equations are coupled with a nonlinear constitutive model derived through thermodynamics. Discretization of the nonlinear problem with a known reference configuration yields a piecewise linear model ideal for transducer design.
