Abstract: | A variant of the multimodulus elasticity theory for isotropic materials is proposed under the assumption that the shear modulus
in Hooke’s law is a constant and the volume modulus depends on the sign of the first invariant of the stress tensor. Plane
problems (plane strain and generalized plane stressed state) and problems of plate bending are considered. Some examples are
given.
