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

Cyclic Degradation Characteristics of Undisturbed Soft Clay considering Anisotropy
Advances in Materials Science and Engineering, 2021 The stress-strain characteristics of soil depend primarily on the previous stress history and stress path, thus related to both the stress magnitude and direction.

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.
