Summary

It has been proposed that the 3-point bending MOR relationship can be used to estimate the stresses in a bar suspended between two supports. Based on this idea, it is further proposed that this concept can be applied to the design of whiteware products to minimize the tendency of the body to exhibit unacceptable pyroplastic deformation. To illustrate this concept, the cross section of dinnerw are plates was altered to reduce the deformation stresses in the plate well. The deformation results were then correlated with samples evaluated using a proposed standard test for pyroplastic deformation.
