“…The present work first summarizes multiaxial fatigue strength of 40CrMoV13.9 steel [40]. The tested material is characterized by four different heat treatments able to assure a high strength at room and elevate temperatures.…”

“…The absence of data from 40CrMoV13.9 steel under multiaxial fatigue loading has motivated this work which is a revised extension of a previous work [40]. Dealing with multiaxial fatigue loading at room temperature, circumferential V-notched and semicircular notched specimens have been tested under combined tension and torsion loading, both in-phase and out-of-phase.…”

“…The tests were performed under uniaxial tension and stress-controlled conditions. A final synthesis of the high temperature results together with previous data from multiaxial tests (at room temperature) on the same material [40] is carried out by means of the strain energy density approach, as recently made for Cu-CoBe alloys tested at elevated temperature [60].…”

The work summarizes a large bulk of experimental data from specimens made of 40CrMoV13.9 steel. The first part of the paper deals with multiaxial fatigue strength of notched round bars tested under combined tension and torsion loading, both in-phase and out-of-phase. The results from multi-axial tests are discussed together with those obtained under pure tension and pure torsion loading from notched specimens with the same geometry. The second part of the paper summarizes data from uniaxial-tension stress-controlled fatigue tests on specimens made of the same steel. Tests are performed varying temperature, from room temperature up to 650°C. Altogether more than 180 new fatigue data are summarised in the present work, corresponding to more than two-years of testing programme. All fatigue data are presented first in terms of nominal stress amplitudes referred to the net area and then re-analysed in terms of the mean value of the strain energy density evaluated over a given, crescent shape volume embracing the stress concentration region. For the specific steel, the radius of the control volume is found to be independent of the loading mode

“…The prediction of the crack propagation direction is essential to understand the fracture behavior of the bi-material joints subjected to the mixed loading conditions. Several fracture criteria have been suggested for evaluating fracture behavior of notches and cracks in homogeneous bodies as well as interface cracks existing between two dissimilar materials [7][8][9][10][11][12][13][14][15][16]. A recent and comprehensive review on brittle fracture criteria can be found in Breto and Lazzarin [9].…”

The present paper summarizes some recent experimental, theoretical and numerical results on brittle fracture of isostatic polycrystalline graphite. The analyses have been carried out on V-notched samples under mixed mode (I+II), torsion and compression loading, considering various combinations of the notch tip radius, opening angle and notch tilt angle. The static strength of the considered specimens is assessed through an approach based on the strain energy density averaged over a control volume. The center of the control volume is located on the notch edge, where the principal stress reaches its maximum value. The correct orientation is obtained by a rigid rotation of the crescent-shaped volume while the size depends on the fracture toughness and the ultimate strength of the material. This methodology has been already used in the literature to analyze U- and V-shaped notches subject to mode I loading with very good results and advantages with respect to classic approaches. The results reported in this new work show, also under mixed mode loading conditions, a good agreement between experimental data and theoretical predictions
