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.

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
