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 Webb29 okt. 2024 · Hertzian contact stress. Hertzian contact theory is a classical theory of contact mechanics and is a very useful tool for engineers and researchers. Even though the derivation of the theory is relatively difficult, the final solution is a set of simple analytical equations relating the properties of the system to the developed stress.
