An alternative way to describe thermodynamically-consistent higher-order dissipation within strain gradient plasticity [PDF]

, 2022
In the context of strain gradient plasticity (SGP), description of higher-order dissipation is the subject of extensive on-going discussions. In most existing SGP theories including thermodynamically-consistent higher-order dissipation, higher-order ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Mechanical properties analysis of non-pneumatic tire with gradient honeycomb structure

Engineering Science and Technology, an International Journal
Non-pneumatic tires have the advantages of high safety and high load-carrying capacity, and have a broad potential for engineering applications. In this paper, the effects of different gradient angles on the static and dynamic performance of honeycomb ...

EFFECT OF TRANSIENT THERMAL GRADIENT ON STRESSES IN COMPOSITE BRIDGES

Proceedings of International Structural Engineering and Construction, 2019
Composite steel-concrete bridges experience higher thermally induced stresses than their concrete and steel cousins. These thermal stresses which can result from support restraints, debris accumulating in expansion joints, or from non-uniform thermal gradients, can lead to significant damage in the concrete deck.

Four simplified gradient elasticity models for the simulation of dispersive wave propagation [PDF]

, 2008
Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Mode I crack tip field with strain gradient effects

, 2000
A plane strain mode I crack tip field with strain gradient effects is investigated. A new strain gradient theory is used. An elastic-power law hardening strain gradient material is considered and two hardening laws, i.e.

Gradient Interfaces Induce the Temporal and Spatial Stress Localization in Gradient Network-Structured Metallic Glasses Composites

Metals
Gradient structure provides an effective approach to improve the combination of high strength and toughness compared to a uniform one. The gradient interfaces or boundaries in gradient-structured metallic glass composites play a crucial role in ...

Spatially distributed damage in sandstone under stress-freeze-thaw coupling conditions

Journal of Rock Mechanics and Geotechnical Engineering, 2022
In the present study, we tried to understand the spatially distributed damage in sandstone samples under the coupled stress-freeze-thaw (SFT) conditions. Firstly, uniaxial compressive stresses (i.e.

Estimation of the impact stress gradient in the range of size effect

Procedia Structural Integrity, 2017
Abstract This paper analyzes the size effect for bending loads. The reduction in fatigue properties in loads with a stress gradient is lower than in loads with homogenous distribution. The proposed test conditions for 1.4301 acid-resistant steel in respect of high-cycle fatigue allowed to verify this phenomenon.
