Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

Advanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Brain Plasticity: Limitations and Possibilities

Neuroscience and Behavioral Physiology, 2017
Biological limitations related to the brain regeneration and stem cells transplantation as well as the factors influencing the brain plasticity following the brain injury, including epigenetic regulatory mechanisms, are presented. Non-invasive transcranial microelectrostimulation is considered as a perspective method of polysystemic influence on ...

Costs and limits of phenotypic plasticity

Trends in Ecology & Evolution, 1998
The costs and limits of phenotypic plasticity are thought to have important ecological and evolutionary consequences, yet they are not as well understood as the benefits of plasticity. At least nine ideas exist regarding how plasticity may be costly or limited, but these have rarely been discussed together.

Limit Analysis for Plastic Plates

SIAM Journal on Mathematical Analysis, 1980
The collapse problem for plate bending is considered as an infinite dimensional mathematical programming problem. The duality between the static and kinematic formulations of limit analysis is proved, and it is shown that limit fields for bending moments and displacement rates exist.

Plasticity, limit analysis, and limiting equilibrium

1994
A system of surface and body forces applied to a body will cause changes in the stresses and strains within it. The changes in strain will usually be partly elastic and immediately recoverable, but may also result in part from irrecoverable plastic yield. As the forces increase, a growing part of the body may reach the limit of its shear strength. Once

Plastic Limit Load

2016
The potential use of the Simplified Theory of Plastic Zones (STPZ) is mainly seen in the simplified determination of strain ranges and accumulated strains caused by cyclic loading, and thus as a basis for service life assessment, which was also the main subject in the previous chapters.
