In-Depth Information
ARAMIS strongly supports the full-field verification of FE-simulations.
Determining material parameters with ARAMIS helps to evaluate and
improve existing material models. The import of FE result datasets allows
one to perform numerical full-field comparisons to FE simulations for all
kinds of component tests. Thus finite element simulations can be optimized
and are getting more reliable).
6.12.1.4  Complete Workflow in One Software Application
The entire measuring, evaluation and documentation process is carried out
within the integrated ARAMIS software.
The full potential of the available hardware is used to capture and evaluate
the measuring area efficiently and with high accuracy (see Figure 6.19).
6.13 X-RayImaging
X-ray imaging applications require unique optical detector system configu-
rations for optimization of image quality, resolution, and contrast ratio. X-ray
photons from multiple anode sources create a series of repetitive images on
fast-decay scintillator screens, from which an intensified image is collected
as a cineradiographic video (or intensified image) with high-speed videog-
raphy Current developments address scintillator material formulation, flash
x-ray implementation, image intensification, and high-speed video process-
ing and display. Determination of optimal scintillator absorption, x-ray
energy and dose relationships, contrast ratio determination, and test result
interpretation are necessary for system optimization [14].
6.13.1 Introduction
Numerous test requirements motivate the development of flash x-ray cinera-
diography systems with multi-anode configuration for repetitive imaging in
closely spaced timeframes. Applications include the following:
• Shaped charge detonations to further understand properties of jet
formation and particulation
• Explosively formed projectile detonations to quantify launch and
flight performance characteristics
• Detonations of small caliber grenades and explosive projectiles to
verify fuse function times and fragmentation patterns
• Performance and behavior of various projectiles and explosive
threats against passive, reactive, and active target systems
• Human effects studies including body armor, helmets, and footwear
