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, WebbUsing these values and Fig. 8 produces a notch sensitivity value of q = 0.58. Using equation (3) and the value for q, the fatigue stress concentration factor ( Kf) was calculated to …

WebbThe CRSS is the value of resolved shear stress at which yielding of the grain occurs, marking the onset of plastic deformation. CRSS, therefore, is a material property and is not dependent on the applied load or grain orientation. The CRSS is related to the observed yield strength of the material by the maximum value of the Schmid factor: WebbThe difference lays on the fact that in the first approach the impact of the section and the curvature is given through the curvature radius of the neutral axis, given by the formula = …
