Abstract
The present article deals with new forms of constraint equations between stresses and strains. Methods for determining material functions and limit parameters (yield, linearity, and analyticity) that are included in these equations have been developed and illustrated by specific examples. Some problems of ensuring the adequacy of the proposed equations are discussed.
