Abstract
An approximate method of solving the variational equation, constructed on the basis of the principle of virtual variation of the deformed state, with a given equation relating the strains (strain rates) is presented. The stress-strain state is then determined from the solution of the above variational equation. The method is demonstrated on an example of the problem of a strip with a rectangular cross section resting on plane-parallel plates.
