“…Overall, the tests performed at 600°C showed larger displacements, especially in the post-peak regime. Although the vertical load vs. actuator displacement curves (Figure 16(a)) show different initial slopes, the horizontal force vs. mode I NOD (Figure 16(b)) showed that the slopes were similar as expected since the Young's modulus of the material is not expected to considerably change for temperatures less than that of the firing process [53][54][55].…”

Refractory castables are utilized in hazardous environments and thus their reliability should be accurately evaluated to avoid incidents. This work aims to measure the fracture energy of a high-alumina refractory with mullite-zirconia aggregates at 600°C. Wedge Splitting Tests were performed on 5 samples with different sintering temperatures. Images were acquired and analyzed via Digital Image Correlation (DIC). Notch Opening Displacements were used to evaluate the fracture energy at room and high tempartures. For the studied material, a 50°C increase in the sintering temperature increased about 30% the fracture energy of the material, which is also higher at 600°C when compared to room temperature measurements.

“…The Young's modulus, E d [1] , obtained from the dynamic test was compared with the results of the static test. The formulas presented in Section 4.5 were used to calculate the Young's moduli, E cd [11] and E cd [111] . The corresponding results are presented in Figure 15.…”

“…These measurements induce minimal deformation, enabling nondestructive measurements even for samples that may experience some degree of degradation in their mechanical properties. [11] Hence, the nondestructive dynamic method is preferred for measuring elastic parameters. The kinetic method [12] is often used to measure the Young's modulus, shear modulus, and Poisson's ratio of metallic materials.…”

The Young's modulus is an essential factor for improving turbine blade design. The present study aims to obtain the flexural frequencies (f1) and corresponding dynamic Young's modulus (Ed) of Ni‐based single‐crystal DD6 across a temperature range of 25–1200 °C using a nondestructive dynamic testing method. The relationship between the elastic constants and various crystal orientations is derived by employing the transformation of the elastic matrix. In addition, finite element (FE) simulation is conducted to calculate the flexural frequency (f1) of the [001] crystal orientation. The findings indicate that the dynamic Young's modulus (Ed) decreases as the temperature increases within the range of 25–1200 °C. Furthermore, the Ed values for different crystal orientations follow the trend: Ed[1] < Ed[11] < Ed[111]. This suggests significant anisotropy in the material. The normalized model, matrix transformation calculation method, and finite element method demonstrate high accuracy in predicting the elastic modulus of DD6, as evidenced by the good correspondence between the fitting curves obtained using the normalization method and the test results. These results have practical applications in engineering, particularly in turbine blade design and other applications, and serve as valuable references for mechanical property testing and finite element simulations.

“…However, even in this field, other expensive complementary techniques had been preferred to IET, such as the ultrasounds analysis, radiography and tomography [8] , which are still the most used non-destructive techniques (NDT) for quality control and certification. In the last years, many notable academic research examples began to spread in the fields of the metallurgy [9] , [10] , [11] , geology [12] and the science of ceramic materials [13] , [14] , [15] . Even if IET data are rich in information content, the main application of the technique consists in the measurement of elastic properties of materials, such as Young’s modulus, shear modulus and Poisson’s coefficient [16] .…”

In the past twenty years, impulse excitation technique (IET) has become a widely diffused non-destructive technique in metal industry field. This success resides in its capability to determine with high precision and accuracy some elastic properties of materials, such as Young's modulus, shear modulus and Poisson's ratio. The technique, which is very fast and non-destructive, consists in exciting a sample by a mechanical input and registering the acoustic output that, once analyzed by Fast Fourier-Transformation (FFT), provides the resonant frequencies of the sample, with a fast data analysis procedure. The approach is thus very easy to be applied to most materials and cost and time effective. Despite these many advantages, IET is still an under exploited technique in academic research centres, that mainly rely on traditional destructive methods for the evaluation of such properties, for instance by the measurement of strain-stress curves. Commercial IET instruments, similarly to traditional ones, have costs spanning from many hundreds to thousands of dollars, limiting their diffusion in academic world but also in small companies with limited R&D or quality control expenses. Non-professional instruments can also give very precise results and can be successfully used in basic research and in quality control even if not certified as commercial ones. Moreover they can be easily customized according to specific user needs and sample features. Since no examples of low cost IET designs can still be found in the scientific literature, we fill the gap in this paper, giving instructions for a self-assembled instrument for IET analysis, with a cost in the range of 70-85 USD. Moreover, the collected calibration data are analyzed to prove that the instrument can be used for other purposes than the common elastic properties determination, but also for a fast and cheap material characterization exploiting a multivariate analysis approach. Calibration results show that IETeasy can be used in both academic and industrial field for quality control purposes as a low-cost, fast and efficient alternative to tensometers. Principal component analysis, applied in this paper for the first time to IET data analysis, was able to distinguish and classify steel from Al or Cu alloys from polymers, but also different steel grades, demonstrating its potential in massive and eventually automatic IET data analysis. Calculated mechanical properties fitted with good approximation the ranges expected for each sample.
