If you took a Belleville style washer (simply supported on the ID) and applied a load to it till it was flat and then increased the load a small amount would the washer "buckle" in the other direction? I think it would but I'm not sure of the internal stresses that would cause it. I'm guessing hoop stresses develop as the washer is flattened and possibly those act to "reverse" the washer. Or maybe radial compressive stresses are developed and they buckle the washer? I'm asking because I might have a use for that in a snap action mechanism. Assume everything stays elastic.
