“…We further simulate failure effects under both monotonic and cyclic uniaxial loadings. To this end, monotonic data and low-tomedium cycle fatigue data in [18] for a low-carbon carbide-free bainitic steel are taken into consideration. Simulation results are calculated with the following parameter values:…”

“…In addition, in the respect of failure effects under either monotonic or cyclic loadings, samples of recent studies may be found, e.g., in [15][16][17][18][19] for experimental results and in [6,7,[20][21][22] for model simulations, and many others. Furthermore, numerous results are available in the study of underlying fatigue micro-mechanisms.…”

A new finite strain elastoplastic 2 -flow model is proposed toward directly simulating cyclic and non-cyclic failure effects of metals. The main novelties of this model are as follows:(1) The usual notion of yielding is rendered irrelevant in a more realistic sense of representing elastoplastic behaviors of metals up to failure;(2) The thermodynamic consistency requirement from the second law may be identically fulfilled;(3) Failure effects under cyclic and non-cyclic conditions may be automatically incorporated as inherent constitutive features, with involving neither additional variables nor ad hoc failure criteria;(4) Hardening-to-softening effects of metals up to failure may be effectively characterized in a unified manner.Simulation results are provided and compared with experimental data for monotonic and cyclic failure effects for both uniaxial and torsional deformation modes. In particular, both the Swift effects and the failure effects of twisted metal tubes are simultaneously simulated for four cases of finite torsion, including free-end and fixed-end torsion under monotonic and cyclic loadings, and accurate agreement with finite strain data for both torsional modes is accomplished for the first time.

“…Figure f shows the occurrence of the transgranular fracture, combined with the microhardness of the Fe‐4 group. Zhou et al have pointed that there is a large amount of bainite in the fatigue fracture area and a certain amount of carbide in the bainite structure; the carbides will show a phenomenon of remelting and morphological changes during the fatigue deformation process, thus causing a transgranular fracture.…”

A vibration‐assisted laser welding experiment of 4.5 mm industrial pure iron is conducted to focus on the influences of vibration parameters on microstructure, fatigue fracture, and fatigue life. The studies show that the microstructure of the joint is optimized under the condition of 1186 HZ vibration frequency and 36.1 m s−2 vibration acceleration; it is also found that a suitable microvibration process can enhance the penetration depth of the joints, reduce the number of columnar crystals, and homogenize the microhardness. In high‐cycle fatigue experiments, the base material (BM) produces fatigue fracture only under the fatigue load of 52% Rm, the fatigue source area under vibration is at the corner of the fracture or at the inside of the weld seam; a functional consequence is that the vibration can increase the fatigue load strength by 1–3 percentage points, and the fatigue life can be increased by 0.8–1.5 multiples. The microvibration can effectively improve the fatigue performance and increase the fatigue life.
