The singular cyclic curve of the Miyauchi test and the corresponding curves of the in-plane torsion test compare well. In contrast to the cyclic curves of DX54D, the Bauschinger-effect is dominant for the high strength steels DP600 and DP800 ( Fig. 4 , Fig. 5 ).
Figure 5 compares the predicitions of the model with test data for a tension-torsion cyclic experiment. The experiment is conducted as follows: first, the specimen is stretched to a strain of ε 0 = 1%; then it is cycled with an axial strain ε = ε 0 cos ( ω t ) and a shear strain γ = 3 ε 0 sin . The influence of strain amplitude on deformation mechanisms and cracking modes during cyclic torsion of the AZ31 magnesium (Mg) alloy was quantitatively investigated via EBSD-SEM characterization. At 0.42% strain amplitude, basal slip was the dominated deformation mechanism throughout the entire fatigue life. At 1.732% strain amplitude, the . The pioneer Smith-Watson-Topper (SWT) is a popular tensile-based fatigue damage model that explicitly considers both Δε and σ max effects on FCI using only Coffin-Manson cyclic parameters to quantify the number of cycles needed to initiate tensile cracks [4], a major asset.Such cracks start on planes perpendicular to the critical point surface, called here . Cyclic torsion fatigue tests with superimposed static torsion loads are performed with VDSiCr spring steel with shot-peened surface in the high cycle fatigue (HCF) and very high cycle fatigue (VHCF) regime. . An existing method to study the VHCF properties of coil springs is to test a great number of springs in parallel in one test frame [1 .

The test results show a significant effect of the chemical composition and temperature of induced martensite creation and the behavior of cyclic strain. . torsion and proportional bending with torsion. The tests of cyclic bending and torsion were performed in low cycle fatigue (where number of cycles to failure is 10 4 –10 5) and high cycle .Phase, time, and frequency graphs also help to measure and observe test occurrences. High-Cycle Crankshaft Fatigue Testing. A high-cycle fatigue test is a standard option for engine crankshaft durability testing. The test engineer applies cyclic torsion onto the component for a defined number of cycles or until they identify fatigue damage. A new method of determining cyclic stress–strain curves for characterizing kinematic hardening of sheet materials is introduced utilizing the in-plane torsion test and optical strain measurement. The test enables the simultaneous recording of multiple cyclic stress–strain curves with different amplitudes of plastic strain at load reversal in one single test and with .
The distinctive feature of cyclic torsion (CT), compared to monotonic torsion, is that the plastic strain in each cycle, which is distributed in a gradient from the surface to the core, tends to be very small (a few percent) at small torsion angles, but accumulates to a very large amount after hundreds of torsion cycles [9, 13].For example, a centimeter-scale sample-level .

Relatively simple fatigue tests have been performed on two common engineering materials, cast ductile iron and low-carbon steel, using two stress states, cyclic torsion and cyclic torsion with . Tests addressing most types of structural failure have been performed: beam-column joints under cyclic loads [9]; beams failing in bending [10], shear [11], and torsion [12]; monotonically-loaded columns [13]; cyclic tests on scaled-down two-dimensional [14] and three-dimensional [15] frame structures and full-scale frames under pushover loads . A 100 kN/1000 Nm closed loop servo-hydraulic axial-torsion test frame was used for the multiaxial experiments.
