We applied the proper orthogonal decomposition (POD) method to extract reduced-order models to efficiently solve nonlinear electromagnetic problems governed by Maxwell's equations with nonlinear hysteresis at low frequency (10 kHz), called static hys

We present a new systematic methodology to efficiently solve coupled electromagnetic problems with nonlinear hysteresis at low frequency (10 kHz), called static hysteresis, by the finite-element method. The methodology integrates a new domain-wall-mo

We formulate a theory of geometrically-exact multilayer beams and one-dimensional plates that account for the through-the-thickness deformation in each layer, in addition to shear deformation. The complete set of nonlinear equations of motion togethe

We review and extend our recent work on a new theory of multilayer structures, with particular emphasis on sandwich beams/1-D plates. Both the formulation of the equations of motion in the general dynamic case and the computational formulation of the

A formulation based on semi-infinite optimization is proposed to obtain accurate thermodynamic phenomenological models over all phases of ferroelectric and ferroelastic materials. The formulation is illustrated with barium titanate (BaTiO/sub 3/) sin

The predictor structural equations for the vehicle models developed in Part I are derived here for use with a new class of predictor/corrector algorithms to solve the mildly nonlinear equations of motion of the vehicle/structure models. Having all ac
