Superior energy absorption of continuously graded microlattices by electron beam additive manufacturing

, 2021
Electron beam melted (EBM) Ti-6Al-4V functionally graded materials (FGM) with continuously graded densities are investigated for dimensional accuracy, compressive properties, fractography and build direction effect in comparison to uniform density ...

Study on the energy absorption performance of bionic tube inspired by yak horn

Mechanics of Advanced Materials and Structures, 2021
To improve the energy absorption of the traditional tube, a bionic tube was proposed based on the structure and mechanical properties of yak horn. The specific energy absorption of bionic tube is 1.25, 0.89 and 1.02 times higher than that of circular ...

Energy absorption during pressing

Soviet Powder Metallurgy and Metal Ceramics, 1968
1. Absolute and relative energy absorptions during the pressing of powders are related to deformation rate by a logarithmic law. 2. The magnitude of energy absorption may be expressed by an equation consisting of two terms. The first term represents an increase in absorption with increasing degree of deformation, and the second a drop in

Energy absorption of riveted structures

International Journal of Crashworthiness, 1999
To study the crash behaviour and the energy absorption capability of subfloor riveted structural sub-components, a basic research program has been undertaken, in co-operation with AGUSTA Helicopters, covering experimental and numerical activities.

Volume absorption laser energy meter for high energy laser by water absorption

Applied Physics B, 2012
Since the energy density of high energy laser can be extremely high and destructive, it is difficult to directly measure the laser energy with custom methods. A volume absorption method directly using water as absorption substance is introduced. In the energy meter, water is pumped into an absorption cavity sealed by a quartz window, and energy ...

“Crash Pendulum” Energy Absorption Test System

Experimental Techniques, 2011
In this study, a novel “crash pendulum” test system which enables the observation of energy absorption capabilities of the materials/structures was developed. The system works with two simple pendulum principles and allows free mass collision axially.

Energy Absorption in Radium Therapy

The British Journal of Radiology, 1946
The paper describes the calculation of the energy absorption or integral dose in a model “patient”, composed of cylinders and elliptical cylinders, from a point source of radium. Calculations have been made for about 800 positions of the source in and near the body.

Energy and Nitrogen Absorption after Biliopancreatic Diversion

Obesity Surgery, 2000
The strict long-term weight maintenance in good nutritional conditions observed after biliopancreatic diversion (BPD) needs to be explained.15 operated subjects were maintained at an isoenergetic and isonitrogenic diet as similar as possible to their usual diet.

Energy Absorption Devices

1972
An ironic consequence of modern highways has been the emergence of new types of accidents. Recent investigations (1) have shown that "running off the road" may be the largest, single cause of fatalities on limited access, multilane roads. According to the 1967 Report of the Special AASHO Traffic Safety Committee ("Yellow Book") (2) the rate of ...
