“…As is reduced, the required value of the coefficient of friction is increased, so that for a square ended punch it is equal to f ¼ 0:543. In one of the very few analytical treatments of complete contact between elastically similar bodies, * Here the notation used by Filippi et al [4] is employed. Fig.…”

The Williams' solution for the state of stress near the apex of an elastic wedge is used to study the traction distribution adjacent to the tip of a complete contact. Assuming that the surfaces remain in contact during loading, the coefficient of friction needed to ensure local adhesion is found. This is compared with that predicted by an analysis of an elastic rectangle clamped between elastic halfplanes and is shown to be consistent. The results are appropriate to all complete contacts between elastically similar components.

“…could approximately be used also for U-shaped notches with a reasonable accuracy (see for instance the paper by Filippi et al (2002). The tangential component of the stress field around a U-shaped notch can be given as follows (Creager & Paris, 1967): are the mode I and mode II notch stress intensity factors (NSIFs), respectively.…”

Ductile failure is investigated experimentally and theoretically in U-notched Al 7075-T6 thin sheets under mixed mode I/II loading. First, several U-notched rectangular sheets are subjected to mixed mode I/II failure tests and the load-carrying capacity of the sheets are experimentally recorded. Then, the Equivalent Material Concept (EMC) is employed in conjunction with the U-notch maximum tangential stress (UMTS) and U-notch mean stress (UMS) criteria to theoretically estimate the load-carrying capacity of the U-notched Al 7075-T6 sheets. It is shown that the experimental failure loads are well predicted by means of both the UMTS-EMC and UMS-EMC criteria. Moreover, the experimental observations and the elastic-plastic finite element analyses indicate that the U-notched aluminum sheets fail by the large-scale yielding (LSY) regime.

“…The SED approach was then extended to blunt U-and V-notches ( [21,22]), by means of the expressions obtained by Filippi et al [23] for the stress fields ahead of blunt notches, and to the case of multiaxial loading [24], by adding the contribution of mode III. It is widely demonstrated that the SED criterion is a reliable approach for the strength determination in a wide range of materials and notch geometries [25][26][27][28], in particular it has been successfully applied to the fatigue assessment of welded joints and steel V-notched specimens.…”

ABSTRACT. Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of this paper is to partially fill this lack of knowledge comparing fatigue strength of uncoated and hot-dip galvanized fillet welded cruciform joints made of structural steel S355 welded joints, subjected to a load cycle R = 0.
