Energy absorption of bio-inspired multi-layered graded foam-filled structures under axial crushing

, 2020
In this paper, an innovative bio-inspired multi-layered graded foam-filled structure (MGFS) mimicking the characteristics of the human skeleton was proposed in an attempt to improve the energy absorption. The proposed structures consisted of three layers

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 ...

Pump Energy Absorption in a Ruby Rod

Applied Optics, 1964
The radial distribution of the pump energy absorbed within a ruby rod when pumped by a helical flash-tube is experimentally measured. The measurement is performed by taking near-field pictures of the emission pattern of the red fluorescence of the ruby.

Energy Transfer and Energy Absorption in Photon Interactions with Matter

2009
This chapter presents a discussion of the important mechanisms involved in energy transfer and energy absorption in an absorber irradiated with an external photon beam. The difference between energy transferred to charged particles in absorber and energy ultimately absorbed in the absorber is attributed to energy radiated from these charged particles ...
