Postcritical stage of plates buckling beyond the elastic limit

The theory of small elastoplastic deformations is used to construct differential equations for investigating the behavior of plates in the postcritical stage. The problem of the cylindrical bending of a rectangular plate compressed in one direction is solved by way of example.Tartu State University.
