Comparison of the Behaviour of Rubber-like Materials under Constant Stress and Constant Strain Conditions

Abstract

MANY experimental data have been published substantiating the use of the Nutting equation, ψ = Sβ σ - 1 tk, where S is shear stress, σ is strain, β, k and ψ are constants, when a series of constant stress experiments is performed. Our own as yet unpublished results confirm the equation over an even wider range of materials.
