Theoretical stress concentration
WebbThe concentration of stress applied on an element can be quantified to factor known as the theoretical stress concertation factor, K t. This factor represents the ratios of the maximum stress and nominal stress (Davies 2015) and is defined according to the equation (1) below. WebbPerson as author : Pontier, L.
