“…The use of IR cameras in the field of experimental mechanics is more and more common [1][2][3][4][5][6][7][8][9][10][11][12][13] in order to quantify the thermomechanical response of materials under load. Most of the time the sought information consists of the kinematic and temperature fields.…”

“…Most of the time the sought information consists of the kinematic and temperature fields. Both are induced by either the mechanical loading [1][2][3][4][5][6][7][8][9][11][12] or the applied thermal history [10,[13][14]. In the first case, temperature elevations are of few degrees Celsius, and accessing the thermomechanical response may provide a better understanding of localization and dissipative phenomena [1][2][3][4][5][6][7][8][9][11][12].…”

“…One of them requires the use of two cameras, namely, one working in the IR and the second in the visible light wavelength range [1][2][3][4][5][6][7][8][9]10,[13][14]. The visible light camera is not sensitive to temperature variations and the DL conservation assumption is satisfied.…”

“…Too large an angle of view may induce (parallax) distortions. The use of a dichroic mirror, which permits one camera to be parallel to the sample surface and the second one at 90° has shown to be a satisfactory alternative [6]. Calibrations are then necessary to relate the zone of temperature variations to displacement fields [8].…”

The thermomechanical behavior of a stainless steel sample undergoing thermal shocks is investigated with an infrared (IR) camera. The temperature and kinematic fields are simultaneously determined exploiting only IR frames. The thermal loading is prescribed with a laser, which gives rise to very high local digital level variations. This effect is addressed thanks to a regularized infrared image correlation (R-IRIC) technique, which accounts for brightness and contrast variations. The resulting digital level residuals are reduced down to less than 1% of the dynamic range, i.e. a level comparable with the noise magnitude, thereby validating the approach.

“…To reach the purpose a new simple method of determination of the energy storage rate distribution has been proposed. The method requires similar measurement techniques like in papers [22][23][24][25][26]. There are simultaneous measurements of temperature and displacement distributions on the specimen surface during a deformation process.…”

Determination of the Energy Storage Rate Distribution in the Area of Strain Localization Using Infrared and Visible Imaging

The presented work is devoted to a new simple method of determination of the energy storage rate (the ratio of the stored energy increment to the plastic work increment) that allows obtaining distribution of this quantity in the area of strain localization. The method is based on the simultaneous measurements of the temperature and displacement distributions on the specimen surface during a tensile deformation. The experimental procedure involves two complementary techniques: i.e. infrared thermography (IRT) and visible light imaging. It has been experimentally shown that during the evolution of plastic strain localization the energy storage rate in some areas of the deformed specimen drops to zero. It can be treated as the plastic instability criterion.
