Test facilities

The picture above shows a test where the Phantom V1610 high-speed camera has been used.

A 7 mm laminated safety glass is hit by a 7.62 calibre lead bullet at a speed of 800 m/s. The camera is set

to a frame rate of 60 000 FPS and exposure time 0.452 µs.

Transmission Electron Microscopy (12)

SFI CASA cooperates with the TEM Gemini Centre at NTNU,

providing SFI CASA access to 5 TEMs: a JEOL double corrected

ColdFEG ARM200F (2013), a JEOL 2100F (2013), a JEOL 2100

(2013), a Philips CM30 (1989) and a JEOL 2010 (1993). The TEM

Gemini Centre also has a well equipped sample preparation lab

and computing facilities.

Cameras

SFI CASA has a FLIR SC7500 infrared camera that can convert

infrared radiation to a visual image that depicts thermal

variations across an object or scene. Thus it can be used

to measure the surface temperature of a specimen under

inelastic deformations. With a resolution of 320x256 pixels the

maximum frame rate is 380 per second, while at a resolution

of 48x4 pixels the maximum frame rate is 31 800 per second

(FPS).

During impact testing of materials and structures, the events

are recorded using high-speed cameras with a maximum frame

rate of 1 000 000 FPS. The research group has access to 2

Photron and 2 Phantom cameras.

Shock Tube Facility (10)

The SIMLab Shock Tube Facility consists of a long tube and a

tank. The tube is 18.2 m long and is divided into six sections.

The tube ends in a 5.1 m

dump tank. The tube starts with

a circular internal cross-section with a diameter of 0.34 m

before it is transformed to a square cross-section of 0.3 m x

0.3 m. Threaded holes in the tube floor enable mounting of test

specimens in the test section, and windows in the test section

and the dump tank allow high-speed cameras to investigate

the structural response during an experiment.

Scanning electron microscope (SEM) laboratory (11)

SFI CASA has access to a SEM lab with the following equipment:

Zeiss SUPRA 55VP (LVFESEM, 2006), Hitachi S-4300SE

(FESEM, 2002), Zeiss, Ultra 55LE, FESEM (2007), Jeol

840 (1989). 3 SEMs are equipped with EDS and

EBSD. The laboratory have in-situ sub-

stage systems for EBSD tensile and

thermo mechanical experiments

(heating, and cooling down

to -60 °C).
