Biaxial – torsion and tension universal testing machine

There are many different products that require biaxial testing. Biaxial loading can be used to measure basic material properties and also the behavior of specific features of interest under biaxial loading conditions. For example, a company may want to test a spinal implant maintaining tensile or compressive force or axial displacement constant and increasing the torque or angle of twist. Another company may want to test a intramedullary fixation device by maintaining torque or angle of twist and increasing load or axial displacement. Many ASTM and ISO standards require biaxial testing.

We used a Croc sandal to show an example of biaxial testing. The Croc was secured to the bottom grip. The strap of the Croc was attached to the top vice grip. At 20 in/min we cycled up and down 1 inch while twisting back and forth 45 degrees. We wanted to see how much wear the sandal strap could tolerate before it became stretched and ineffective. Think about the materials that you are testing. Could you use a biaxial testing machine to get more information to your customers about the features of your products?  This test was performed using an ADMET eXpert 2610 5kN dual column system with a 10Nm torque actuator and a triaxial load cell. The system can be configured according to your specifications.
