“…In particular, our method was attempted to be used to estimate the fatigue lifetime of specimens of 304SS [54], pure titanium [14], titanium BT9 [14], SNCM439 [55], SNCM630 (A) [56] and SNCM630 (B) [55] Figure 8 confirms that the MMCCM applied along with the -MVM was capable of accurately predicting the sequence effect in fatigue, the critical value of the damage sum, D cr , being taken equal to unity for all the investigated materials. The next step in the performed validation exercise was considering short VA load histories.…”

“…Further, the MMCCM used in conjunction with the -MVM was seen to be capable of accurately taking into account the effect of superimposed static strains as well (see Figure 6b). Subsequently, our fatigue assessment method was used to predict the fatigue lifetime of samples of Al7075-T651 [41], S460N [48] and 304SS [55] tested under combined CA axial and torsional sinusoidal/triangular strain signals of different frequencies. By focussing attention on the considered sinusoidal load histories, it is possible to observe that under a ratio between the frequency of the axial channel, F x , and the frequency of the torsional channel, F xy , equal to 2, the resulting stress/strain history relative to the critical plane was composed of one shear stress/strain cycle and two normal stress cycles (see Path F in Figure 7).…”

“…The N f,e vs. N f chart of Figure 7 shows that the proposed approach was highly accurate in modelling the damaging effect of combined CA axial and torsional strain signals of different frequencies. As to the obtained level of accuracy, it is important to point out that it was reached by taking the critical value of the damage sum, D cr , equal to unity for Al7075-T651 [41] and S460N [48], whereas, as suggested by Sonsino [20], it was set equal to 0.27 for 304SS [55].…”

“…Finally, if *, * and * are used to denote the angles defining the orientation of this plane together with the associated critical direction MV, the stress and strain components relative to the critical plane can directly be determined via Eqs (A5) to (A8), where =*, =* and =*.

This paper investigates the accuracy of the so-called Modified Manson-Coffin Curve Method (MMCCM) in estimating fatigue lifetime of metallic materials subjected to complex constant and variable amplitude multiaxial load histories. The MMCCM postulates that fatigue damage is maximised on that material plane experiencing the maximum shear strain amplitude. In the present investigation, the orientation of the critical plane was determined through that direction along which the variance of the resolved shear strain reaches it maximum value. Under variable amplitude complex load histories, this direction was also used to count the resolved shear strain cycles via the classic Rain-Flow method. Further, the degree of multiaxiality and nonproportionality of the time-variable stress states at the assumed critical locations was directly quantified through a suitable stress ratio which accounts for (i) the mean value and the variance of the stress perpendicular to the critical plane as well as for (ii) the variance of the shear stress resolved along the direction experiencing the maximum variance of the resolved shear strain. The accuracy and reliability of the proposed approach was checked against approximately 650 experimental data taken from the literature and generated by testing un-notched metallic materials under complex constant and variable amplitude multiaxial load histories. The sound agreement between estimates and experimental results which was obtained strongly supports the idea that the proposed design technique is a powerful engineering tool allowing metallic materials to be designed against constant and variable amplitude multiaxial fatigue by always reaching a remarkable level of accuracy. This approach offers a complete solution to the strain based multiaxial fatigue problem.

Unterschiedliche Methoden für die Lebensdauerabschätzung unter variablen Beanspruchungsamplituden wurden basierend auf Versuchen mit Proben aus dem Stahl ZStE340 analysiert und miteinander verglichen. Einige der bekanntesten und am meisten angewendeten Methoden wurden gewählt: der Schädigungsparameter PSWT; der PJ-parameter, basiert auf der Bruchmechanik kurzer Risse; das Non-Linear-Continuous Damage Model (NLCD), basiert auf der Kontinuumsmechanik und der Energieparameter von Ellyin. Jede Methode wurde dargestellt und diskutiert. Die Basis für die Ermittlung der Abschätzungsgüte waren experimentelle Versuchsergebnisse aus ZStE340 Proben im Ausgangszustand und nach dem Spaltprofilierprozess. Der Schädigungsparameter PSWT erwies bessere Ergebnisse und ist für die Lebensdauerabschätzung von ZStE340 geeignet

In this article, the finite element analysis (FEA) combined with the fracture mechanism of rubber was used to predict the fatigue life of the radial tire carcass rubber. Five tire structures with different angles were designed under the premise of ensuring the same height of carcass cord and radius of curvature. The fatigue life prediction of tires was performed using the Lake-Lindley model in combination with finite element models and crack extension tests. The location and causes of damage in 11.00R20 load radial tires were analyzed, and the effect of sleeve cord angle on tire mechanical properties and fatigue performance was investigated to predict the fatigue life of the radial tire carcass rubber. The simulation test results are within 10% error when compared with the actual durability test results, which can fully meet the daily design development of tire enterprises. The fatigue life prediction method can shorten the development cycle and reduce the development cost of tires. Improving tire durability is important for reducing the use of petrochemical materials and environmental pollution.
