In this study, we established a theoretical photothermal model and its experimental
validation for an infinitely long solid with an inner corner of arbitrary opening angle, with the …

The flash method, known as the most used experimental technique to measure the thermal
diffusivity of solids, has been adapted to cylindrical highly diffusive and heterogeneous …

We extend the applications of photothermal radiometric diagnostics to continuously curved
cylindrical surface solids using lock-in thermography (LIT) imaging, in which both the …

In this work, we establish a theoretical model for a cylindrical rod of radius R with opening
angle θ illuminated by a modulated incident beam. The model uses the Green function …

This work aimed to develop non-destructive control procedures, either automated or semi-
automated, for evaluating the quality of thin welded joints using active thermography …

In this paper, we establish a Green-function based theoretical model for evaluating solid
multi-layered spherical samples which are illuminated by a frequency modulated incident …

Analytical solutions of the diffusion equation for a radially N-layered cylinder were derived in
the steady-state, frequency, and time domains. Solutions for axially infinite and finite …

Equivalence of the normalized thermal-wave fields between curved and flat surfaces under
certain conditions is investigated based on theoretical models of cylindrical, spherical, and …

In this study, a theoretical model is established for a wedge-like solid with an open sector
surrounded by walls of radius R of a cylindrical rod illuminated by a modulated circular …

A theoretical model for evaluating solid multilayered spherical solids heated by a frequency-
modulated light beam using the Green function method is presented. The specific thermal …
