Linear stress formula

Nettet6. des. 2016 · A notched tensile specimen of steel with notch radius 0.7 mm (stress concentration factor α=2.15 ), was analyzed with an alternating load of up to 40 kN (stress ratio R = -1). In fig. 1 the stress amplitude at the base of the notch can be seen for the v. Mises and max. principal normal stress. Linear elasticity is a mathematical model of how solid objects deform and become internally stressed due to prescribed loading conditions. It is a simplification of the more general nonlinear theory of elasticity and a branch of continuum mechanics. The fundamental "linearizing" assumptions of linear elasticity are: infinitesimal strains or "small" deformations (or strains) and linear relationships between the components of stress and strain.
