The Influence of the Shaft Mass on the Natural Pulsation of the Free and Forced Transverse Vibrations and Having a Homogeneous Wheel Mounted at the End

Scientific Bulletin of Valahia University: Materials and Mechanics
The paper aims to study the influence of the mass of the shafts on the natural pulsations of the free and forced transverse vibrations of an elastic system formed by a fixed shaft and a homogeneous wheel for two cases: free vibrations and forced ...

A STUDY REGARDING THE DAMPING CAPACITY OF COMPOSITE BARS REINFORCED WITH FIBER GLASS AND THE MATRIX MADE WITH AMBRESIT [PDF]

Fiabilitate şi Durabilitate, 2016
In this paper, we have built some composite bars with the reinforcement made by fiber glass which is randomly disposed and the matrix made by ambresit. Then, in order to study the samples free vibrations, we have clamped the bars at one end and we left

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Analysis of thin-walled beams with variable monosymmetric cross section by means of Legendre polynomials

Studia Geotechnica et Mechanica, 2019
This article deals with the vibrations of a nonprismatic thin-walled beam with an open cross section and any geometrical parameters. The thin-walled beam model presented in this article was described using the membrane shell theory, whilst the equations ...

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

Advanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
