A form of the elastic potential for high-elastic material / G. Z. Sharafutdinov, P. V. Chistyakov. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2013. № 2. P. 24-29 [Moscow Univ. Math. Bulletin. Vol. 68, N 2, 2013.].
A form of the elastic potential is proposed. A number of experiments and a procedure of determining the material constants and functions are considered. With the use of known experimental data, an expression of the elastic potential for the vulcanized rubber is obtained as an example.
Key words: strains, stresses, invariants of strain tensor, constitutive relations, calibration experiments, material constants and functions.
