A Biaxial Tension-Compression Test Method for Composite Laminates
Journal of Composites Technology and Research, 1994Development of a test system and associated experimental procedure for evaluating the strength of composite laminates under an in-plane biaxial tension-compression (BTC) stress state is presented. A description of the BTC test system and specimen is given.

Development of a biaxial compression test apparatus for granular materials
AIP Conference Proceedings, 2013A set of two-dimensional biaxial compression testing system was developed to investigate the stress-strain behavior and its change with the micro-structure of granular materials. The specimen was assembled using small metal bars with elliptical section. Load was then subjected in both horizontal and vertical directions.

Biaxial Compression Testing of Refractory Concretes
1983In the past, the design of large refractory lined process vessels, such as used in coal gasification, has been based on operating experience. During the 1970’s, efforts were funded by the Department of Energy (DOE) to develop mathematical models that would predict the thermo-mechanical behavior of refractory concrete lined coal gasification process ...

Elastic stability in biaxial testing with cruciform specimens subjected to compressive loading
Composite Structures, 2020Abstract This work presents the main aspects that should be taken into account to design biaxial experiments with cruciform specimens in the presence of compressive loading, applied on the arms of the sample by means of compression plates. The global buckling of the cruciform specimen and the local instability of the rectangular-shaped central region

Key Engineering Materials, 2021
Numerical process design leads to cost and time savings in sheet metal forming processes. Therefore, a modeling of the material behavior is required to map the flow properties of sheet metal. For the identification of current yield criteria, the yield strength and the hardening behavior as well as the Lankford coefficients are taken into account.

Abstract Recycled aggregate concretes (RACs) made of building wastes can achieve good environmental and economic benefits. Since fire is one of the most common disaster in modern high-rise buildings, the strength, deformation and bearing capacity of recycled concrete structures under high temperatures should be carefully studied in design.

THE CONTROL SYSTEM OF THE FATIGUE TEST STAND UNDER BIAXIAL TENSION-COMPRESSION
Experimental Techniques, 2010In this paper, a system for control of the hydraulic test stand for biaxial tension—compression of cruciform specimens was presented. The system is equipped with six control loops and two compensators of amplitude, which improve the machine operation. The elaborated mechatronic system based on the biaxial strength machine realizes the planned fatigue ...

Abstract In this study, the behavior of recycled steel fiber reinforced concrete (RSFRC) is investigated through uniaxial cyclic compression and biaxial tests conducted on 56 cubic specimens with four admixtures of RSF-content. The results obtained from cyclic compression tests show that the presence of RSFs reduces the damage of specimens in the ...
