Sizing the Depth and Width of Narrow Cracks in Real Parts by Laser-Spot Lock-In Thermography
(MDPI, 2021-09-28)
We present a complete characterization of the width and depth of a very narrow fatigue crack developed in an Al-alloy dog bone plate using laser-spot lock-in thermography. Unlike visible micrographs, which show many surface ...
Quantifying the width and angle of inclined cracks using laser-spot lock-in thermography
(Elservier, 2021-06-30)
In this work we introduce a method to determine the width and the orientation of tilted cracks. This method
combines laser-spot lock-in thermography and calculations of the sample temperature by means of finite ...
Laser-spot step-heating thermography to measure the thermal diffusivity of solids
(Elsevier, 2021-06-15)
In this work we show that laser-spot step-heating thermography allows measuring the thermal diffusivity of solids accurately. It consists in illuminating the sample surface with a continuous-wave focused laser spot and ...
Crystallographic, magnetic and magnetocaloric properties in novel intermetallic materials R3CoNi (R = Tb, Dy, Ho, Er, Tm, Lu)
(Elsevier, 2021-02-04)
A family of novel intermetallic R3CoNi with heavy rare earth ions has been synthesized (R = Tb, Dy, Ho, Er, Tm, Lu) and a study of the crystal structure of these phases performed. All the compounds adopt the rhombohedral ...
Determining the thermal diffusivity and the principal directions on anisotropic moving samples with laser-spot thermography
(Elsevier, 2021-05-24)
We propose a method to measure the thermal diffusivity of (an)isotropic samples moving at constant speed using laser-spot thermography with continuous illumination. The method does not require previous knowledge of the ...
