Theoretical stress formula

Webbstress concentration factor is defined by the following equation: K f = 1 + q ∙ (K t - 1), where K t Designis the theoretical stress concentration factor for the given geometry, and q is the notch sensitivity ratio of the material. For a notch sensitivity ratio of 1, the full stress concentration factor is used. If the notch WebbFig. 1: Critical stress vs slenderness ratio for steel, for E = 200 GPa, yield strength = 240 MPa. Euler's critical load is the compressive load at which a slender column will suddenly bend or buckle. It is given by the formula: [1] where , Euler's critical load (longitudinal compression load on column), , Young's modulus of the column material,
