.... A simple shear problem of a metal layer between rigid boundaries is analyzed. Two stages of plastic deformation are considered. In stage I, the plastic strain is taken to be zero at the boundaries. Stage I ends when a specified magnitude of the plastic strain gradient is attained at the boundaries...

... solution. For soft metallic materials, metals at high temperature, rough surfaces, or dry contacts with high friction coefficient, the yield stress within the material could be easily exceeded even at low normal load. This paper presents the effect of a cuboid of uniform plastic strain in a half-space...

...Christian F. Niordson; Viggo Tvergaard In metal-ceramic systems the constraint on plastic flow leads to so high stress triaxialities that cavitation instabilities may occur. If the void radius is on the order of magnitude of a characteristic length for the metal, the rate of void growth is reduced...

...D. L. Marshall; M. E. Taylor; Y. Ivshin; G. Diderrich; T. J. Pence We consider a boundary value problem for a flat plate of an originally ductile metal that is subject to surface corrosion. Corrosion is modeled with the aid of two mobile interfaces. The leading interface is an oxidation front where...
