In this study, we propose a new post processing algorithm, using stable low-rank decomposed pseudo restored heat flux based on the ensemble variational Bayes tensor factorization (EVBTF-RPHF) algorithm for performing periodic square wave thermographic nondestructive testing (thermographic NDT). Previous studies have shown that both RPHF and EVBTF can separately improve detectability of thermography by enhancing some defect features. However, methods are limited their particularly...
Composite film materials offer several advantages, such as high strength-to-weight ratios, flexibility, durability, or cost-effectiveness, which make them ideal for a wide range of applications across various industries. However, microporous defects in the material compromise its durability and air-tightness. Thus far, few works have been performed on inquiring non-destructive testing methods intended detection composite materials. In this study, automatic is achieved by using thermal...
One-sided thermal non-destructive testing (TNDT) is of vital importance in aerospace composites to monitor structural degradation, as well detect subsurface defects. The objective this study evaluate simultaneously the diffusivity and characterize defects within carbon fiber reinforced polymer (CFRP) composites. In paper, a novel one sided TNDT technique presented which relies on creating an artificial inflection point by multiplying front-surface temperature evolution nth power time, where...
This paper is a tribute to Dr. Ermanno Grinzato, who passed away 10 years ago (1952–2012). We will review the original research and contributions that Grinzato made infrared thermographic non-destructive testing data analysis. proposed developed some novel techniques, including evaluation of construction quality in civil engineering, inspection art objects, detection corrosion, etc. A number his concepts were further into new application areas, such as ultrasonic thermography. was on...
The primary objective of this review is to present a close-up outlook at both the terminology and principles modelling data processing in thermal nondestructive testing (TNDT). It shown that development advanced treatment algorithms related analysis heat conduction solids with subsurface defects. TNDT practically used industrial areas where possible technical failures cause essential financial and/or human losses.
This paper describes the use of laser vibrometry and thermal non-destructive testing for detecting defects in GFRP composite by applying a single test procedure. The involves averaging vibration amplitudes over an entire frequency spectrum accompanied frequency-phase analysis. Such procedure may lead to suppression low signals, produced smaller deeper defects, higher signals conditioned larger shallower defects. fusion results obtained with both NDT was used enhance defect detectability....
Abstract A transient method of thermal nondestructive testing is applied to detect subsurface delaminations in fresco plaster as a part restoration work that being conducted Italy. two-dimensional cylindrical model used estimate temperature distribution materials with defects various sizes and depths. The possibility thickness up 30 mm illustrated. choice heating technique, which supposed be really ancient frescoes powerful enough create reasonable temperatures signals, considered. Test...
