Mechanical Properties and Dynamic Response of Lightweight Reinforced Concrete Beam [PDF]

open access: yesEngineering and Technology Journal, 2012
The study is conducted to perform two goals: The first geal is to produce a lightweight concrete using major components which are locally available with some standard admixtures.Many mixtures are prepared using many ratios of superplasticizer (SP) and ...

Calcium dynamically alters erythrocyte mechanical response to shear

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2020
Red blood cells (RBC) are constantly exposed to varying mechanical forces while traversing the cardiovascular system. Upon exposure to mechanical stimuli (e.g., shear stress), calcium enters the cell and prompts potassium-efflux. Efflux of potassium is accompanied by a loss of intracellular fluid; thus, the volume of RBC decreases proportionately (i.e.,

Mechanical response of two different molecular weight polycarbonates at varying rates and temperatures [PDF]

open access: yesEPJ Web of Conferences, 2021
Polymers are widely used for lightweight design in industrial applications, such as helmets and car bumpers, where the most common causes of failure or damage are dynamic impact events.

Dynamic Response to Mechanical Stimulation in Myobrasts.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000
An experiment was carried out to investigate the morphological response of mechanically stimulated myoblasts that were cultured on a collagen-coated silicone ribbon and were subjected to tension for 6 hours. Images of the cells were taken by a CCD camera and input into a computer every 10 minutes for 8 hours.

Analysis of dynamic mechanical response in torsion [PDF]

open access: yesJournal of Rheology, 2016
We investigate the dynamic response of industrial rubbers (styrene-butadiene random copolymers, SBR) in torsion and compare against common small amplitude oscillatory shear measurements by using a torsion rectangular fixture, a modified torsion cylindrical fixture, and a conventional parallel plate fixture, respectively, in two different rheometers ...

Mechanical Structure Design and Experimental Study of Gamma-ray Monitor for Small Satellite Payload

open access: yesApplied Sciences, 2022
In this paper, a novel mechanical structure for a gamma-ray monitor (GRM) is designed for a small satellite payload. Its structural stiffness, strength and dynamic response are directly related to the performance of the novel GRM, which must meet the ...

MECHANICAL CHAINS: IDENTIFICATION OF DYNAMICAL RESPONSES

open access: yesProceedings of the Mongolian Academy of Sciences, 2017
Approaches for dynamical responses identification in example of system with three freedom degrees with tie between two of outside elements are offered. First approach bases on using of mathematical models-analogues of automation control theory, second approach bases on rules of transformation of design schemes of chains theory.

Mechanical behaviour of additively manufactured elastomeric pre-buckled honeycombs under quasi-static and impact loading

open access: yesMaterials & Design, 2022
Selective laser sintering has been used to manufacture different structural variations of a pre-buckled circular honeycomb. The mechanical behaviour of these structures has been examined under both quasi-static and dynamic impact loading.
