✦ Synopsis

A frictional material model is investigated with respect to the existence and development of a regularized strong discontinuity within the constitutive framework of plasticity theory. It appears that the condition for the existence of such a discontinuity is identical to the classical bifurcation criterion for band shaped bifurcation in the rate of deformation field. The model behaviour is also discussed beyond onset of localization, for a band with fixed orientation, where the state variables are allowed to change.

## Abstract In this work, a very simple and accurate model for the microwave‐assisted drying of laminar bodies, based on their dielectric properties, is developed and tested over a laminar material such as leather. Several assumptions are made to simplify the obtained expressions. The results show
