Abstract: | Summary The problem considered here is that of the plane-strain compression of a long symmetric strip of a three-layered material
between rigid, parallel, rough plates. Two combinations of layers are examined: (a) a viscoplastic material placed between
two layers of a rigid/perfectly plastic material, and (b) a rigid/perfectly plastic material placed between two layers of
a viscoplastic material. Closed-form solutions are presented for each combination, and qualitative differences between these
solutions and solutions obtained for homogeneous materials are discussed. A possible effect of asymptotic behaviour of the
solution in the vicinity of maximum-friction surfaces on the general structure of the solution is mentioned.
