Stability of an annular plate of a shape memory alloy

Analytical solutions using various hypotheses are obtained for the problem of buckling of an annular circular plate of a shape memory alloy in the forward or reverse thermoelastic phase transformations under uniform radial compression. It is established that, despite the axial symmetry of the body geometry, loads, and boundary conditions, the minimum critical loads for annular plates correspond to nonaxisymmetric buckling modes, in contrast to continuous plates.
