Abstract : The thin circular plate considered in this investigation is simply supported along its edge and made of an incompressible rigid, viscoplastic material. The stress analysis is based on the model of Bingham solid (Fluidity and Plasticity, pp. 215218, McGrawHill, N. Y., 1922) A linearized theory of viscoplasticity is used to treat the bending of the plate, where it is subjected to a uniformly distributed transverse load. A solution to this boundaryvalue problem consists of the stress field, the velocity field, and the associated field of the rate of deformation. A theorem according to Prager (Linhere it is subjected to a uniformly distributed transverse load. A solution to this boundaryvalue problem consists of the stress field, the velocity field, and the associated field of the rate of deformation. A theorem according to Prager (Linearization In ViscoPlasticity, Brown University Tech. Report No. 64, pp. 57, Providence, R. I. 1960) shows that the field of the rate of deformation is unique.
