Summary

The influence of strength after fire and residual stresses on the load-strain response to enamel failure was studied. Standard sheet tensile blanks were enameled and then pulled to failure. The load-strain response was analyzed and modeled as a laminate composite. It was found that the strength after fire of a steel plays a significant role in the strength of an enamelware component. Essentially, the enamel fails only after going into some amount of tension. Since the residual compressive stress in the enamel is significant, the component must be strained a considerable amount before this occurs. As a result, the enamel failure load is almost always influenced by the strength of the steel.
