“…The conducted fatigue tests have conformed the ability of the new fatigue sensor application for the fatigue damage monitoring of aviation components. Deformation relief which is formed on the surface of the sensor in the test portion basically is the system of the extrusions, intrusions, persistence slip bands, i.e., the evolution of the sensor surface state is similar to the processes, previously investigated on the surface of alclad aluminium alloys specimens near the stress concentrators [7,12,13].…”

It was shown by tests conducted at the National Aviation University (Kiev, Ukraine) that fatigue damage of metal structures may be estimated by sensors with the surface relief pattern to indicate the accumulated fatigue damage. The nature of the deformation relief has been investigated by the light, scan and transmission microscopy, as well as by a new nano-interferometer, developed at the National Aviation University. Fractal analysis of the surface patterns based on box-counting method has proved the efficiency of fractal geometry application for additional quantitative description of such surface structures. The evolution of deformation relief parameters on the sensors surface is determined by the process of the sensor and construction fatigue damage accumulation.

“…Appropriate materials for fatigue sensors manufacturing are well known aluminium alloys D16AT, V95, 2024T3, 7075T6, covered by the layer of pure aluminium. This layer acts as an indicator of fatigue damage because the deformation relief appears on the surface under the action of repeated loads [7].…”

“…[14,15] In previous works, DIC and AE techniques have been simultaneously applied to study the crack profile, localized plastic strain evolution and full/local strain fields of bulk materials, especially metal alloys with different scales. [16][17][18][19][20] However, precise matches have not been established between AE and DIC techniques to elucidate failure mechanisms of alloys. On the other hand, strain fields and crack profiles of brittle coating/ductile substrate systems are much more complicated than that of bulk materials.…”

In this paper, we proposed a non-destructive evaluation method combined digital image correlation (DIC) with acoustic emission (AE) techniques, which was used to in-situ monitor interface failure and internal damage of brittle coating/ductile substrate systems under different size scales by bending tests. Measurements of full/local field strain fields by DIC in the segmented coating clearly show typical heterogeneous failure process and successfully clarify several controversial assumptions introduced in theoretical models. AE results effectively reveal the damage evolution of cracking nucleation, propagation and coating spallation of the ceramic coating by combining wavelet transform with traditional parameter analysis under external loads. The conclusions show that there is a good relationship between digital image correlation and acoustic emission signals with the aid of test time during the coating failure, which can be applied to judge cracking formation and coating delamination, and to obtain the most important critical experimental data. As an example, several crucial mechanical properties of a thermal barrier coating system including fracture strength, fracture toughness and shear strength were determined.
