Abstract:

The thin circular plate considered in this investigation is simply supported along its edge and made of an incompressible rigid, visco-plastic material. The stress analysis is based on the model of Bingham solid Fluidity and Plasticity, pp. 215-218, McGraw-Hill, N. Y., 1922 A linearized theory of visco-plasticity is used to treat the bending of the plate, where it is subjected to a uniformly distributed transverse load. A solution to this boundary-value 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 boundary-value 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 Visco-Plasticity, Brown University Tech. Report No. 64, pp. 5-7, Providence, R. I. 1960 shows that the field of the rate of deformation is unique.
