“…Some of the setups include a disc heated by induction on the periphery [1][2][3][4][5][6][7][8][9][10][11][12], triangular blade heated by induction [13], electrical heating of tube followed by water splashing to induce thermal shock [14][15][16][17][18], hot dipping of cylinders in molten aluminum [19,20], laser heating [21,22], focused halogen lamps heating [23,24], convection/combustion heating [25,26], furnace heating with water quenching [27,28] and actual dies [29,30]. Out of these experimental setups most researchers have worked on the heated disc problem.…”

a b s t r a c tIn this paper, a new framework to correlate the experimental data of the 304L stainless steel under multiaxial fatigue loadings using a reference curve identified from the experimental data of standard uni-axial fatigue tests is proposed. A total of 15 available fatigue crack initiation criteria are tested on the experimental data of 225 fatigue tests collected from EDF (formerly known as Electricity of France), its partners and the literature. Based on the computational results, it appears that most of the crack initiation parameters of the 15 available criteria can be used to correlate the experimental fatigue data for the 304L stainless steel under uni-axial loadings. Under bi-axial loadings, most of these parameters appear not to be quite consistent. Two criteria are modified in order to better correlate the experimental fatigue data under bi-axial loads. A simple statistical approach to evaluate the consistency of the crack initiation criteria is also proposed. Based on the limited available experimental fagtigue data and within the new framework in this paper, the computational results show that the equivalent crack initiation parameters of the Varvani-Farahani's criterion, the modified Lagoda-Macha-Sakane's criterion and the modified Varvani-Farahani's criterion can be used to correlate the experimental fatigue data under both uni-axial and bi-axial loadings for the 304L stainless steel. These criteria may be used to predict the fatigue life of the material under different loading and testing conditions by using the experimental data from the standard uni-axial fatigue tests.

“…These experiments are very time consuming and physical parameters are not always well documented, considered, and/or controlled. Hence, the development of crack network is also under investigation from full-field numerical simulations provided a random set of crack locations and sizes is chosen for each simulation [3,4,[10][11][12][13]. The technique's advantage is the explicit accountability of the thermal stress gradient versus material depth and how the shielding and coalescence effects occur between the network cracks.…”

a b s t r a c tA new finite element method is proposed to model the evolution of cracks in a 3D lattice under mechanical and thermal fatigue loading. This step-by-step method, based on the separation of initiation and propagation phenomenon, is tuned by fitted entrance parameters which command fatigue laws. It is founded on linear elasticity assumptions, and the crack's evolution is taken into account by a so-called element deletion method. After the algorithm of the model is presented, two examples of mechanical and thermal fatigue are considered. The evolutions of different crack network characteristic parameters as a function of the number of cycles is proposed and match, at least qualitatively, the general trends observed experimentally.
