The stress-strain relations developed by the author in previous work for use beyond the elastic range have been simplified and applied to thin plates. Different expressions are given for these relations in the elastic, the elasto-plastic, and the plastic zones which may arise in a thin plate. The stability of plates compressed beyond the elastic range is studied and examples are given of exact and approximate solutions.
