Plastic bifurcation paradox for circular and rectangular plates
Abstract eng: Exact bifurcation analyses are performed for circular and rectangular plates bonded to elastic foundations. The stresses before bifurcation are biaxial for rectangular plates and equibiaxial for circular ones. Rival theories of strain hardening plasticity model the plate material. For circular plates, the theories yield almost the same results regardless of the foundation. For rectangular plates, the results are similar for equibiaxial loading. Large differences emerge for non-equibiaxial loadings.
