A THEORY FOR CREEP OF CERAMIC BODIES UNDER CONSTANT LOAD

Abstract
The plastic flow and elastic behavior of ceramic materials is treated using a statistical mechanical relaxation theory. It is found necessary to treat creep as involving two, and, in some cases, three relaxation mechanisms. The methods necessary for treating such non-Newtonian Dow are developed here for creep for the first time. The results obtained are in accord with expectations on the basis of reports of others for flow at constant rate of loading and constant rate of strain for other materials.
