Ratcheting fatigue behaviour of advanced structural materials at their service temperatures [PDF]

Scientific Reports
Ratcheting fatigue behavior is a critical phenomenon in structural materials undergoing cyclic loading, particularly when combined with nonzero mean stress or multiaxial stress states.

Depth-dependent ratcheting strains of young and adult articular cartilages by experiments and predictions [PDF]

BioMedical Engineering OnLine, 2019
Background Ratcheting strain is produced due to the repeated accumulation of compressive strain in cartilage and may be a precursor to osteoarthritis.

Ratcheting in structural adhesives

Polymer Testing, 2021
When adhesively bonded joints are subjected to a cyclic load, they will primarily behave viscoelastically. Under certain loading conditions, they can also experience permanent deformation, or ratcheting.

Ratcheting-Fatigue Behavior of Harmonic-Structure-Designed SUS316L Stainless Steel

Metals, 2021
Stainless steels with harmonic-structure design have a great balance of high strength and high ductility. Therefore, it is imperative to investigate their fatigue properties for engineering applications.

Rate-dependent ratcheting characteristics of high density polyethylene subjected to cyclic pulsating compression

Polymer Testing, 2023
Monotonic and pulsating cyclic compression tests were performed systematically based on high density polyethylene (HDPE). The compressive creep behaviors were further implemented to compare with the ratcheting deformation under the same peak stress level.

Local Ratcheting at the Notch Region of Non-Press-Fitted and Press-Fitted Al 7075-T6 Samples Undergoing Asymmetric Stress Cycles

Metals, 2023
The present study evaluated the ratcheting response of notched and press-fitted Al 7075-T6 specimens under stress-controlled asymmetric cycles. The degree of the interference fit (DIF) directly influenced the magnitude and the rate of progressive plastic

Ratcheting of 316L stainless steel thin wire under tension-torsion loading [PDF]

Fracture and Structural Integrity, 2016
A series of cyclic tension-torsion tests under symmetric shear strain and asymmetric axial stress control in various loading paths are conducted on 100 ?m-diameter 316L steel wires applying a micro tensiontorsion fatigue testing apparatus. The ratcheting
