Abstract
Taking advantage of some recent closed form expressions for the strain energy density in a control volume embracing the notch tip, some simple expressions are derived for the Notch Stress Intensity Factors of an infinite array of double symmetric lateral notches and edge notches under tension loading. The new expressions are applicable to narrow notches when the ratio between the notch depth and the plate width, a/W, is lower than 0.025 providing very accurate results. © 2012 Springer Science+Business Media B.V.File in questo prodotto:
