Occurrence of plastic collapse under ratcheting due to gravity and seismic loading
Mechanical Engineering Journal, 2022 The most dominant failure mode of piping components under seismic loading is fatigue failure with ratcheting. While it was confirmed via the experimental tests in the past, the Primary stress limit is applied to seismic loading to prevent plastic ...

Ratcheting of Granular Materials [PDF]
Physical Review Letters, 2004 We investigate the quasi-static mechanical response of soils under cyclic loading using a discrete model of randomly generated convex polygons. This response exhibits a sequence of regimes, each one characterized by a linear accumulation of plastic deformation with the number of cycles.

Controlling heat ratchet and flow reversal with simple networks
Physical Review Research, 2023 We investigate ratcheting heat flow in simple networks consisting of a one-dimensional nonlinear chain with a self-coupled loop when the average thermal bias is zero.

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture
Angewandte Chemie, EarlyView.Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Numerical Investigation of Preload Process of Bolted Joint with Superelastic Shape Memory Alloy
Metals, 2018 A phenomenological constitutive model is developed to describe the uniaxial transformation ratcheting behaviors of the superelastic shape memory alloy (SMA) by employing a cosine–type phase transformation equation with the initial martensite ...

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.

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
