“…Small punch tests (SPTs) have been successfully employed for decades for the mechanical characterization of different metallic [1][2][3][4][5][6] and non-metallic materials [7,8]. One of the advantages of this test lies in the very small size of the specimens employed, with a characteristic length (side or diameter) smaller than 10 mm and thickness of 0.5 mm or lower.…”

The aim of this paper is to demonstrate the applicability of the Small Punch Test (SPT) in the mechanical characterization of polymers, following previous achievements in metallic materials. For this purpose, different polymers with a wide variation of tensile properties were examined. The applicability of this type of test to characterize polymeric materials is especially interesting when these products are in the form of films, as their greatly reduced thickness enables an easy preparation of the SPT specimens.\ud \ud All the polymer materials were characterized by means of small punch and tensile tests. The tensile stress-strain curves were compared with the load-displacement SPT curves and the representative SPT parameters were defined accordingly. A good correspondence was found between the tensile elastic modulus and the initial slope of the SPT plot (Slopeini/t), with t being the specimen thickness, and a good correlation was also observed between the tensile yield strength and the SPT Pym/t2 parameter. On the contrary, no corresponding relationship was found to predict the ultimate tensile strength or the failure elongation, since these properties depend greatly on the stress state of the test (uniaxial or biaxial).Peer ReviewedPostprint (author's final draft

“…Subsequently, the theoretical interplanar crystal spacing of β-Sialon face of (101) with different Z values could be calculated from Eqs. (1) to (3). When the Z value is 2 the calculated interplanar crystal spacing (d value) of the face (101) is 2.7027 Å, while the d value is 2.7217 Å for the Z value with 3.…”

“…These features have resulted in the widespread use of these refractories as functional elements in steel smelting casting systems [1][2][3][4]. Advancements in steel metallurgical technology, such as achieving high smelting quality, clean steel and ultra-low carbon steel, require alumina-carbon refractory compositions with a long service life and low carbon content [4][5][6][7][8].…”

“…Preliminary investigations show that the strength of the investigated material is very sensitive to the microstructure properties. [3,4] Thus, a specimen manufacturing process has to be chosen that results in a similar microstructure, as the carbon-bonded filter. In this study, disk-shaped specimens prepared either by slip casting or by spraying are compared.…”

Open cell ceramic foam filters are used for metal melt filtration to reduce non-metallic inclusions. A new generation of multifunctional filters made of carbon-bonded alumina is investigated within the Collaborative Research Center CRC 920. These filters have to withstand high thermal and mechanical loads. Motivated by the problem of the filters integrity, a mechanical characterization of the bulk material is necessary. In the Ball On Three Balls Test (B3B) miniaturized disk-shaped specimens are loaded with a spherically tipped punch until failure occurs. With the help of the measured load displacement curve the fracture stress is calculated and analyzed by means of WEIBULL distribution.
