Some exact solutions in the design of technically orthotropic axisymmetric plates

Abstract

The equations governing the problem of minimum reinforcement of technically orthotropic axisymmetric plates have been integrated for some simple cases. The exact solutions are compared with the previously known approximate solutions. It is shown that, at least in the cases investigated, the latter predict with great accuracy the required total minimum reinforcement, but not its distribution in the radial and tangential directions or in the inner and outer regions of the plate.
