On the Plastic Strain Accumulation in Notched Bars During High-Temperature Creep Dwell [PDF]

Journal of Mechanics, 2020
ABSTRACTStructural integrity plays an important role in any industrial activity, due to its capability of assessing complex systems against sudden and unpredicted failures. The work here presented investigates an unexpected new mechanism occurring in structures subjected to monotonic and cyclic loading at high temperature creep condition. An unexpected

Low Cycle Fatigue Life Assessment Based on the Accumulated Plastic Strain Energy Density [PDF]

Materials, 2021
The accumulated plastic strain energy density at a dangerous point is studied to estimate the low cycle fatigue life that is composed of fatigue initiation life and fatigue crack propagation life. The modified Ramberg–Osgood constitutive relation is applied to characterize the stress–strain relationship of the strain-hardening material.

Accumulation of plastic strain in Zircaloy-4 at low homologous temperature [PDF]

Journal of Nuclear Materials, 2015
Abstract Time-dependent strain accumulation in Zircaloy-4 was evaluated at 294 K, i.e., homologous temperature (T/Tm, where Tm is the melting temperature) of 0.14, to ascertain the mechanical response in fuel cladding material, even at the time of storage.

Research on the Accumulated Plastic Strain of Expansive Soil under Subway Loading

Applied Sciences, 2023
Expansive soil near Hefei Xinqiao International Airport was selected as the research focus. The effects of different loading modes on the dynamic strain of the saturated remodeled expansive soil was investigated by indoor dynamic triaxial tests and the effect of three factors, intermittent loading ratio, static deviatoric stress, and cyclic stress ...
