Hysteresis in flow through porous media
Porous media flow is described by a class of PDEs whose model equation is represented by the Richards equation with soil-moisture hysteresis term. We assume that the hysteresis is represented by the Preisach hysteresis ...

Inversion of hysteresis and creep operators
The explicit inversion formula for rate dependent Prandtl?Ishlinskii operators is extended to cases without the threshold dilation condition. This solves a problem in hysteresis and creep modeling of magnetostrictive behavior....
