Mathematical representation of Hooke''s law at major strains
The field of applicability of the defining relation of the isotropic elastic solid used in linear theory of elasticity is estimated. On the basis of experimental data on the uniaxial extension the improved representations of Hooke''s law with the account of geometrical nonlinearity are acquired. The calculation results of the pure flexure of the beam on linear theory of elasticity, strength of materials and the offered improved relations are compared.
