Comparative assessment of Young’s modulus measurements of metal–ceramic composites using mechanical and non-destructive tests and micro-CT based computational modeling

Toward better understanding of the effect of fiber distribution on effective elastic properties of unidirectional composite yarns

“…12) [22]. similar to an earlier study [24]. Further, these other methods, unlike the Halpin-Tsai equations, do not account for variation in the geometry of composite particulates.…”

“…First, XMT has been used to image a consolidated UD yarn containing glass fibers. Then, a series of finite-element simulations were carried out on both randomized micro-scale RVEs (hereafter called "Randomized Young's modulus [24], or on a random chopped fiberglass composite and its Young's modulus as well as in-plane shear modulus [25], or on a short steel fibers composite and its equivalent orientation tensor [26]). Also recently a new approach for compressing and reconstructing complex information on the two-dimensional microstructures of disordered (random) particulate media has been introduced [27], by means of a finite set of tiles assembled via a stochastic tiling algorithm.…”

Rhenium doped chromium–alumina composites for high-temperature applications

“…The present paper is focused on the development of novel Cr/Re/Al 2 This work further extends the authors' recent research efforts on bulk Cr/Re/Al 2 O 3 composites reported in [14][15][16] and contains preliminary results for Cr/Re/Al 2 O 3 composite coatings.…”

Optimal contact sensor mounting position for impulsive excitation technique

“…Therefore, the optimal sensor mounting position through the time domain is not valid. The main objective of the impulsive excitation test is to obtain the natural frequency information of the system, part or sample (Węglewski et al, 2013;Zhu and Emory, 2005). Accurate values of natural frequencies are important for further analysis.…”
