Journal Title: Frattura ed Integrità Strutturale - Year 2009, Vol 3, Issue 9
Abstract
In this paper, a non-local equivalent stress is calculated by solving a second order differential equation of implicit type. The solution is obtained by assuming a linear elastic constitutive behaviour and the maximum principal stress as equivalent stress. Fatigue behaviour of steel welded joints is taken into account and a general fatigue scatter band is proposed. The non local stress is computed, namely the effective stress, by means of a completely numerical solution of local elastic stress field. In complex 3D welded details the critical point turns out from the analysis and it is not assumed a priori.

Three-dimensional effects on cracked components under anti-plane loading
The existence of three-dimensional effects at cracks has been known for many years, but understanding has been limited, and for some situations still is. Understanding improved when the existence of corner point...
