โœฆ Synopsis

Elasto-plastic deformation in layered media of dissimilar materials was investigated using the finite element method. Three interfacial conditions were studied : a perfectly bonded interface, a crack lying along an interface and a crack normal to the interface. The initiation and the rate of growth of the plastic zone depend on the stress singularities. Soft material in a layered medium can generally take a greater load than the same material in a single phase body. Case studies were presented to compare the stress solutions along the interface and to illustrate the development of plastic yielding for both plane stress and plane strain.

Based on continuum damage mechanics (CDM), the paper presents a non-linear ยฎnite element formulation for a Timoshenko beam. A layered approach has been adopted to simulate the progressive growth of damage and plasticity from extreme ยฎbers towards the neutral axis. An isotropic continuum damage 1-D m
