Stress intensity factor: new and improved estimates

Abstract

In this paper we give new estimates from above and from below of the Stress Intensity Factor on an open bounded and convex domain \(\Omega \subseteq \mathbb {R}^2\). This analysis is a continuation of the study that we have done in Ascenzi et al. (Appl Math Comput 158:597–617, 2004), Ascenzi (Ann Univ Ferrara Sez VII (NS) 47:41–56, 2001) and Livieri et al. (Acta Mech 176:95–105, 2005) and that started from the paper of Oore and Burns (J Press Vessel Technol 102:204–211, 1980).
