“…The C/C specimens used in this study were evaluated by using the modified Parker technique where the sample was heated with a short heat pulse delivered by a Xenon flash tube through a slit-mask thus ensuring the measurement of two lateral diffusivities x a and y a if to rotate the mask by the 90 o angle. In details, this methodology was described elsewhere [3][4][5][6]. …”

This study is intended to establish quantitative relationships between impact damage energy and some thermal NDT parameters in application to carbon/carbon composites. When applying uniform optical stimulation, the used approach involves the synthesis of effusivity/diffusivity images respectively in one-and two-sided test procedures. Ultrasonic stimulation of composites has also proven to be attractive due to its special applicability to detect micro-cracks. However, quantitative relationships between temperature signals and impact energy are still to be studied.

“…The period from 1990 to 2010 was marked by intensive international collaboration of Tomsk Thermal NDT laboratory with many known TNDT experts/teams: Maldague (Canada) [11], Grinzato, Bison and Marinetti (Italy) [12], Thomas et al, Burleigh (USA) [13,14], Lahiri et al (India) [15], Guo Xingwang (China) [16], Swiderski (Poland) [17], Kauppinen (Finland) [18]. ThermoCalc-2DM is a version of ThermoCalc-2D, but a disk-like defect can be placed in a shell made of a different material, thus modeling, for example, a landmine in soil surrounded by thin air gaps, or a Teflon insert in a composite surrounded by modified host material.…”
