    Notes: A set of non-linear and coupled equations governing the thermomechanical deformations of a viscoplastic body undergoing simple shearing deformations is integrated in time by using the forward-difference Galerkin finite-element (FDGFE) method and the Crank-Nicolson-Galerkin finite-element (CNGFE) method. In the latter scheme the number of unknown functions is increased so that the governing equations contain only first-order spatial derivatives. It is shown that the solutions obtained by the two methods agree qualitatively; however, the CNGFE method seems to introduce some damping into the system for non-polar materials, but none for dipolar materials.

    Notes: Steady-state finite plane strain deformations of a uniformly rotating rubber-covered roll contacting a rigid plane surface have been studied by the finite element method. The rubberlike material has been modelled by a constitutive relation recently proposed by Christensen. Both the hydrostatic pressure within an element and the nodal displacements are taken as independent variables. For a constant indentation of the roll cover, the effect of the change in the thickness of the rubberlike layer, the speed of rotation and the values of the material moduli on the total load required to cause the indentation are presented.
