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.

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.

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.

Research on the Biaxial Tensile Strength Test and Formula of Cement Concrete
Advanced Materials Research, 2011This paper mainly focuses on the cracking problem of concrete structures, researches on the biaxial tensile strength of cement concrete. The biaxial tensile instrument is used for material test, the biaxial tensile strength formula is proposed, and the theoretic formula is deduced by Hill criterion.

Assessment of Systems for Carrying out of Planar Biaxial Tensile Test
Applied Mechanics and Materials, 2014Determination of materials behavior subjected to complex stress state corresponding to certain operating conditions is one of the main objectives of material testing. Biaxial and triaxial tests are necessary to facilitate understanding of the materials behavior subjected to complex loadings.

Plastic Material Model Identification Using Dic on Biaxial Tensile Test
2007The accuracy of a Finite Element Simulation for plastic deformation strongly depends on the chosen constitutive laws and the value of the material parameters within these laws. The identification of those mechanical parameters can be done based on homogeneous stress and strain fields such as those obtained in uni-axial tensile tests and simple shear ...
