Back stress in strain hardening of carbon nanotube/aluminum composites

Materials Research Letters, 2018
As demonstrated by the loading–unloading tests and the modeling of the grain size effect and the composite effect, mainly owing to the back stress induced by CNTs, carbon nanotube/aluminum (CNT/Al) composites exhibit higher strain hardening capability ...

A Newtonian Model for the Quantum Gravitational Back-Reaction on Inflation [PDF]

, 2001
Quantum gravitational back-reaction offers a simultaneous explanation for why the cosmological constant is so small and a natural model of inflation in which scalars play no role.

Evidence Against Combined Effects of Stress and Brain Stimulation on Working Memory

Open Psychology, 2020
The effect of stress on working memory has been traced back to a modulation of the prefrontal cortex (PFC). We investigated the effects of neuromodulation of the left dorsolateral prefrontal cortex (lDLPFC) after exposure to psychosocial stress through ...

Back Analysis of the Initial Geo-Stress Field of Rock Masses in High Geo-Temperature and High Geo-Stress

Energies, 2020
In a high geo-temperature environment, it is rarely reported that geo-temperature has been considered during a back analysis. This may cause the initial geo-stress field that is obtained by a back analysis to be wrong.

Thermodynamic dislocation theory: Bauschinger effect

, 2018
The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here to simulate the stress-strain curves for crystals subjected to anti-plane shear-controlled load reversal.

Back-Stress and Its Evolution during Primary Creep in Particle Strengthened Nickel Superalloys

Crystals, 2020
According to Eshelby’s theory, inelastically inhomogeneous inclusions in a metallic matrix give rise to a distribution of internal stresses. In the case of particle strengthened materials, such as nickel base superalloys, the presence and evolution of ...

Hebrew stress: Back to the future [PDF]

Acta Linguistica Academica, 2018
The paper addresses historical changes in the stress system of Hebrew, attending to the difference between Biblical Hebrew (script-based) and contemporary Hebrew (attested), and predicting the system of post-Hebrew; on the basis of experimental evidence and words from the periphery of the lexicon, it is predicted that the stress system of post-Hebrew ...

Study of the response of CFRP composite laminates to a laser-induced shock [PDF]

, 2014
Laser-induced shock yields to a local tensile stress within a sample. This high strain rate stress can be used to verify the bond strength between two layers.

Back stress quantification in heterostructured metals: a comparative study of tension-compression and loading-unloading-reloading tests

Materials Research Letters
The Bauschinger effect, characterized by a reduction in yield stress upon load reversal, plays a critical role in both springback prediction and the understanding of back stress-mediated strengthening in emerging heterostructured materials. In this study,

Perspective on hetero-deformation induced (HDI) hardening and back stress

Materials Research Letters, 2019
Heterostructured materials have been reported as a new class of materials with superior mechanical properties, which was attributed to the development of back stress.
