要約:	Title screen This study presents a comprehensive methodology for characterizing air-filled finite-size defects in materials with varying thermal properties using pulsed thermal nondestructive testing (TNDT). We numerically solve the three-dimensional heat transfer problem for 729 test cases encompassing defects with different lateral dimensions, depths, and thicknesses in both metallic and non-metallic materials. The analysis yields maximum temperature contrasts and their corresponding observation times, while investigating the influence of defect geometry on thermal signatures. An analytical expression for predicting observation times is derived to complement the numerical results. The computational results are fitted with polynomial functions to enable rapid estimation of optimal TNDT parameters. This approach provides a practical framework for evaluating detection limits across a wide range of material properties and defect geometries. System-wide analysis reveals mean errors of 60 % for temperature contrast evaluation and 36 % for determination of observation times. Experimental validation using reference samples demonstrates measurement accuracies of 14–35 % for temperature contrasts and 2–8 % for observation times. The proposed inverse solution achieves particularly accurate depth characterization (<14 % error), though thickness estimation shows greater variability (up to 61 % error) Текстовый файл AM_Agreement
