Together the four specimen grips are oriented to provide biaxial application of force to a test specimen.Abu-farha, FadiKhraisheh, MarwanF. Abu-Farha and M. Khraisheh, “Uniaxially-Driven Controlled Biaxial Testing Fixture” (U.S. patent application pending, filed May 2008)....
In biaxial loading states, moreover, the cross reading of axial and shear deformation measurements is highly affected by quality of the fixture. The test specimen temperature of below 30 °C was monitored and maintained additionally by means of a load-specific adaptation of the test frequency in...
The mechanical response of the CSPs is also studied under uniaxial tensile loading and compared with the biaxial test response to understand the effect of the applied stress field. The experimental strain is measured using the digital image correlation (DIC) technique. Fractography and EDS have ...
Biaxial fatigue tests were performed on thin-walled tubular 1045 steel specimens in a test fixture that applied internal and external pressure and axial lo... A. Varvani‐Farahani,TH Topper - 《Fatigue & Fracture of Engineering Materials & Structures》 被引量: 9发表: 2010年 Cracking Mechanisms...
Biaxial test samples require simple geometries and minimal surface preparation, reducing fabrication costs and handling hazards. This study investigated the TRS of polycrystalline UO 2 fuel forms at room temperature using a ball-on-ring test fixture . Pellets were fabricated from UO 2 powder using ...
(2018) who carried out tests on glass beams using a four-point bending fixture with three different load spans. A mean strength increase was observed as the surface area exposed to tension decreased, even though the number of tests was rather limited. The use of a four-point bending fixture...

The Ball-on-Three-Balls-test (B3B) and the Ring-on-Ring-test (RoR) were conducted on alumina discs and compared based on Weibull-Theory. The influence of various intermediate layers was evaluated. To support these findings, Finite-Element-Analysis was conducted to analyze the effects of devia...
First, uniaxial loading tests on samples made from L450 steel were carried out, followed by an FE analysis validated by the test results, particularly on the formation and propagation of the Lüders band. In the FE analysis, the UDU model was used as the constitutive model. Different ...
A special fixture was used to fix the AE sensors on the rock samples and the loading blocks. A coupling agent was applied between the sensors and the sample to achieve a good coupling effect. The AE acquisition threshold was set to 55 dB to eliminate the background noise and the multi-...
