This report deals with the stability of flat panels of E-glass reinforced epoxy plastic when subjected to axial compression and the factors affecting this stability. Prime attention was paid to the methods of data interpretation. The results demonstrate in a conclusive fashion that the so termed strain reversal technique has no value in the interpretation of the data obtained in such tests. They show in an equally positive manner that both the Southwell and large deflection methods give identical results and these are associable with theoretical load levels. For ease of use the large displacement interpretation method is preferable.
