On numerical integration for effective stress assessment at notches

Enrico Maggiolini, Paolo Livieri, Roberto Tovo


This paper presents a numerical method for non-local stress assessment by means of a general FE
tool and the local stress field. Unlike usual calculations by means of a numerical PDE solver, a more general
numerical integration is used. Different solutions are compared theoretically and numerically by evaluating the
results obtained by two different FEM commercial software. The application of the non-local tension field is
applied to the strength assessment of notches, welded joints and cracks.
