Biaxial tensile tests of the porcine ascending aorta
Journal of Biomechanics, 2016One of the aims of this work is to develop an original custom built biaxial set-up to assess mechanical behavior of soft tissues. Stretch controlled biaxial tensile tests are performed and stereoscopic digital image correlation (SDIC) is implemented to measure the 3D components of the generated displacements.

A 30 ton biaxial tensile testing machine
Journal of Strain Analysis, 1969The machine is intended for a flat-plate testpiece, one face of which has to be unobstucted throughout the test. Plates up to 36 in long, 27 in wide, and 3/4 in thick can be accommodated. Hydraulic rams actuated by air-hydraulic pumps exert completely independent tensions on cruciform test pieces through spherical bushes.

Use of the hydraulic bulge test in biaxial tensile testing
International Journal of Mechanical Sciences, 1979Abstract The effect of the geometry of the bulge and the measuring procedure on the determination of biaxial stress-strain curves is examined. The shape of the top of the bulge is shown to be nearly spherical irrespective of the anisotropy of the sheet, while the meridional strains may differ from the balanced biaxial strain state.

A Study on the Cracked Specimen for Biaxial Tensile Loading Test
Key Engineering Materials, 2006In the recent years, the studies on the mechanical behaviors of various materials subjected to biaxial loading have been worked since they are more complicated and intrinsically different from those under the simple uniaxial condition. The cruciform specimen without any slots has been commonly used for the goal so far.

Numerical Study of Cruciform Specimens for Biaxial Tensile Tests
Volume 14: Emerging Technologies; Materials: Genetics to Structures; Safety Engineering and Risk Analysis, 2016This paper presents a numerical study of different geometries of cruciform specimens for biaxial tensile tests. The aim of these specimens is to be used on fixtures for biaxial tests mounted in universal testing machines. For the study, a model of isotropic material for steel sheet metal specimens was considered. Thus, only the mechanical properties of

An Apparatus for Biaxial Strength Testing of Standard Tensile Specimens
Journal of Testing and Evaluation, 1992Abstract A novel, low cost testing apparatus has been designed for the application of biaxial stress on standard tensile spectmens. The apparatus independently applies compressive loading perpendicular to a tensile load. The compressive load is transferred through a compression pad, applying hydrostatic pressure to the test section.

Design of Biaxial Tensile Fixture for Fatigue Testing on Uniaxial Tensile Testing Machine
Journal of Testing and EvaluationABSTRACT Cruciform specimens are commonly used to simulate the complex stress states experienced by engineering components in real-world applications. Biaxial tensile testing of these specimens typically requires specialized biaxial tensile testing machines that are rare and expensive.

Optimisation of Cruciform Test Specimen for Biaxial Tensile Testing of Sheet Metal
Advanced Materials Research, 2011One of the most restricting aspects of the biaxial tensile test for sheet metal is the design of the cruciform specimen. Although specimens of the cruciform type have previoussly been investigated quite extensively, no standard geometry for the cruciform specimen exists.

Design of geomembrane specimen for biaxial tensile testing
Geosynthetics InternationalA numerical–experimental framework is developed to optimise the design of geomembrane specimens for biaxial tensile testing. Specifically, the geometry and adhesive bonding method of specimens are optimised to maximise strain in the central measuring region while reducing premature failure caused by stress concentrations outside this region.

Optimal Design of a Disk-Shaped Specimen for Biaxial-Tensile Fatigue Testing
Journal of Testing and Evaluation, 1996Abstract A relatively simple apparatus has been proposed for conducting biaxial-tensile fatigue tests using an annular disk specimen with a reduced testing section. It makes use of a conventional hydraulic testing machine so that the uniaxial force is converted into radial forces extending the disk specimen.
