Biaxial mechanical testing of human sclera

Journal of Biomechanics, 2010
The biomechanical environment of the optic nerve head (ONH), of interest in glaucoma, is strongly affected by the biomechanical properties of sclera. However, there is a paucity of information about the variation of scleral mechanical properties within eyes and between individuals. We thus used biaxial testing to measure scleral stiffness in human eyes.

Biaxial Testing of Membrane Biomaterials: Testing Equipment and Procedures

Journal of Biomechanical Engineering, 1991
A testing facility for measuring the biaxial mechanical properties of highly deformable membranes is described. Forces are applied, via strain-gauge force transducers, to four points on each side of an initially square 12 to 25 mm membrane sample to produce biaxial extensions of up to 80 percent of undeformed length.

Biaxial Testing of Unidirectional Carbon-Epoxy Composite Using Biaxial Iosipescu Test Fixture

Journal of Composite Materials, 1997
In this study, the biaxial Iosipescu test fixture has been employed to determine the failure properties of a unidirectional carbon-epoxy composite subjected to combined shear and transverse tensile stresses. The range of possible biaxial stress states has been extended by varying the fiber orientations in the Iosipescu specimens.

The Biaxial Wheel Test Rig

SAE Technical Paper Series, 1985
<div class="htmlview paragraph">Operating load simulation tests are presently to the greatest extent the state of engineering for the development of new running gear components, because of their great strength of statement. These genuine operating load simulation tests on car wheels are only possible with relatively expensive test rigs.</div ...

Biaxial fracture testing of rubber compounds

2011
ABSTRACT: In this work the fracture toughness of natural rubber compounds under biaxial tensile load- ing condition was evaluated determining the J-integral by finite element analysis. To this aim a sound consti- tutive equation from tests under simple well-identified stress states such as tensile and plane strain test con- figurations was first ...

A Review of Biaxial Test Methods for Composites

2007
This paper will give an overview of the existing biaxial test methods for composite materials from the early beginning till the currently used methods. An evolution in both the biaxial testing capabilities and the applied inspection methods will be shown.

Biaxial vibration-testing installation

The Journal of the Acoustical Society of America, 1980
The installation comprises means for subjecting a specimen-holder table to vibrations with respect to a massive support structure in two perpendicular directions, and guiding means which are independent of the vibration means. The guiding means are located between on the one hand the table and at least one connecting member and on the other hand the ...

A versatile biaxial testing platform for soft tissues

Journal of the Mechanical Behavior of Biomedical Materials, 2021
Uniaxial testing remains the most common modality of mechanical analysis for biological and other soft materials; however, biaxial testing enables a more comprehensive understanding of these materials' mechanical behavior. In recent years, a number of commercially available biaxial testing systems designed for biological materials have been produced ...

Biaxial tensile tests of the porcine ascending aorta

Journal of Biomechanics, 2016
One 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.

Biaxial testing of composite tubes

Experimental Mechanics, 1985
The development of a tubular test specimen for the characterization of advanced composite-material lamina and laminate mechanical properties is presented. The specimen design and supporting analyses are given for a practical tubular specimen that minimizes end effects.
