Constitutive Relations for a Rubber Cord under Three-Dimensional Stress States / Sheshenin S.V., Demidovich P.N., Chistyakov P.V., Bakhmet'ev S.G. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2010. ? 3. P. 32-35 [Moscow Univ. Mech. Bulletin. Vol. 65, No 3, 2010. P. 55-58].

The transverse modulus of a rubber cord is experimentally determined. It is shown that, in the framework of the effective layer model, it is problematic to find both the bending stiffness and the lateral compression stiffness with equal adequacy.

Key words: mechanics of composite materials, rubber cord, mechanics of tires, effective elastic modulus, homogenization.
