Ronald Rivlin was an outstanding figure in the development of modern nonlinear continuum mechanics in the second half of the 20th century. Much of his research is characterized by the innovative, systematic and effective use of methods based on invar

Many interesting phenomena have been observed in layers of granular materials subjected to vertical oscillations: these include the formation of a variety of standing wave patterns, and the occurrence of isolated features called oscillons, which alte

A procedure has been developed in previous papers for constructing exact solutions of the equations of linear elasticity in an inhomogeneous isotropic linearly elastic material in which the elastic moduli depend in any specified manner on a specific

In the conventional theory of finite deformations of fibre-reinforced elastic solids it is assumed that the strain-energy is an isotropic invariant function of the deformation and a unit vector A that defines the fibre direction and is convected with

We present a number of general results relating to nonlinear viscous and viscoelastic anisotropic fluids with transversely isotropic symmetry. Among the topics considered are some kinematic results, the effect of kinematic constraints, the stress res

There has been a great deal of interest in the problems of modelling cables and ropes. A recent review by Cardou and Jolicoeur [Appl. Mech. Rev. 50 (1997) 1] considers the modelling of a cable which consists of a central core surrounded by one or sev

An account is given of the non-dilatant double-shearing theory of plane flow of granular materials, and it is shown that the theory may be formulated as a special form of hypoplasticity theory. It is shown that according to this theory, simple sheari

This paper presents two applications of the double-shearing theory for flow of granular materials under gravitational forces for axially symmetric flow. In the first the material is contained in a vertical circular cylinder which compresses the mater
