Biaxial Tensile Testing

AbstractMost conventional material testing apparatuses are unable to assess poly-nanofibers sheets in biaxial directions. This study reports the design and prototyping of a biaxial tensile apparatus which can measure the mechanical property of a poly nanofibers patch. Several samples were assessed using the designed biaxial tensile testing machine and results recorded. Function of the apparatus was validated versus convention methods and outcome confirmed that it is accurate and reliable for testing poly nanofibers patch.

Biaxial Tensile Testing

The 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. Satisfactory direct-load readings were obtained form pressure gauges.

Biaxial Tensile Testing

One 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. Using a specifically designed pantograph apparatus for operation in a standard tensile testing machine, various cruciform specimens were analysed experimentally. Finite element modelling of the specimens was also conducted to establish optimum specimen geometry. Through a process of optimisation, a standard cruciform specimen was designed which can be used to accurately predict the mechanical behaviour of cold rolled low-carbon steel when formed in multiple directions simultaneously.

7A09 aluminum alloy is served as an important structural material in many fields. In this paper, power spinning of semi-continuous casting 7A09 aluminum alloy tube blank was carried out, and the effects of process parameters, such as spinning temperature and roller feeding ratio, on spinnability were analyzed, further the mechanical property was tested on a tensile testing machine. The results show that: at 300°C and 1.2mm/r roller feeding ratio, semi-continuous casting 7A09 aluminum alloy tube blank has good spinnability; after spun, the yield strength is increased 44%, and elongation is increased 130%.

Eggshell Membranes

The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from different bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the membrane in latitudinal direction. TIRAtest 27025 tensile testing machine equipped with a 200 N load-cell was used. Tensile deformation exhibits both non-linear as well as linear region. The experiments were performed at five loading velocities 1, 10, 100, 400 and 800 mm.min−1. The main parameters describing the eggshell strength increase with the loading rate. This dependence exhibits the same qualitative features as the rate dependence of the eggshell strength.

Biaxial Tensile Testing

ABSTRACT The mechanical behavior of filled rubbers depends on the maximum stretch previously reached and consequently on the induced stress softening. This softening effect is referred to as the Mullins effect. Current investigations point out that the Mullins effect exhibits a significant directional dependence, which calls for an anisotropic material model. But for the formulation and validation of anisotropic material models, there is still a lack of suitable experimental data. For this the purpose, experiments based on chloroprene rubber (CR) are reported. To trace the anisotropic Mullins effect, the standard test method for characterization of the isotropic mechanical behavior must be extended. The appropriate type of specimen enables us to perform multiple load steps with alternating load directions. After repeated stretching in the same direction, a subsequent first uniaxial loading in any other direction is characterized by a stiffer stress–strain behavior compared with the stabilized curve of the previous primary load. Hence, the experimental results confirm the deformation-induced anisotropy. To identify the multiaxial material behavior after the prestretching in one direction, a biaxial tensile-testing machine is developed. A specific property of the biaxial tensile-testing machine is the independent control of both the loading axes. Thus, the rubber material can be subjected to arbitrary loading histories. Therefore, a cross-shaped specimen with four arms is used. Multiple slits parallel to the sides on each arm ensures the homogenous uniaxial load condition in the primary load. In the secondary load step, the loading axis, which was previously inactive, is moved in a uniform manner as the master axis or in any arbitrary defined ratio. The experimental results confirm the deformation-induced anisotropy of the Mullins effect. In summary, the material behavior significantly results from the deformation mode and the loading direction applied in the loading history.

Market Needs

Starch is an inexpensive abundant product and is totally biodegradable in a wide variety of environments and allows the development of totally degradable products for specific market needs. We study the influence of starch on the degradation behavior of plastic films prepared by mixing the film grade polyethylene pellets with different amounts of starch. The mechanical strength of the polymer films were measured by Instron 5560 Tensile Testing Machine and observed that with the addition of starch mechanical strength decreases. As biodegradation rate increases with starch addition, 25 to 35% starch can be added safely in the plastic shopping bag without changing its strength significantly.
