On Lamb's plane problem in micropolar viscoelastic half-space with stretch.
On the nonlinear theory of micropolar bodies with voids.
On the propagation of acceleration waves in thermoelastic micropolar medias.
On the stability of multipolar elastic materials.
In 1964, Green and Rivlin [1, 2] proposed two non-standard theories of continua. Both papers concerned non-simple materials: the first considered deformation gradients of higher order than the first as dependent variables; and the second, which generalised the first, treated materials whose kinematic state was not completely detemined by the deformation function, but was also dependent upon some multipolar deformation functions. In both theories the existence of higher order stresses is fundamental.In...
