Fatigue testing machines are generally designed to identify the danger point or location of failure of a test piece of material that has been subjected to a series of stresses. This measures the durability or lifespan of a material or component, as well as the maximum load that it can withstand. After a sample is loaded into the fatigue tester, it is stressed until either a pre-determined number of cycles is reached or the material experiences failure. These tests can be performed with either constant amplitude or using servo hydraulic test machines.

| Description | The ElectroForce Planar Biaxial TestBench instrument offers superior control and unparalleled performance in material and soft tissue characterization. Using this instrument, you can assess mechanical anisotropy and stress-strain relationships in samples that range from engineered devices, includingThe ElectroForce Planar Biaxial TestBench instrument offers superior control and unparalleled performance in material and soft tissue characterization. Using this instrument, you can assess mechanical anisotropy and stress-strain relationships in samples that range from engineered devices, including wearable sensors and wound repair meshes, to tissues such as skin, pericardium, and heart valve leaflets. This instrument can be configured with either two or four ElectroForce linear motors mounted on a horizontal baseplate and load cell options for each axis of loading.
Key Features: - Superior performance: choose parameters for your test protocol without compromising accuracy, including force, displacement, frequency, and wave shape (loading profile)
- Controllability: precisely characterize different materials by controlling specific experimental parameters, including load, displacement,and strain control (with theDigital Video Extensometer (DVE))
- Tailored for specific research needs: upgrade to a 4-motor configuration or add accessories such as hook or clamp tensile grips, heated saline bath, sterile BioDynamic chamber, or extended stroke and torsion actuators
- Integrated non-contact strain measurements: perform 2-D strain measurements in a physiologically-relevant environment with the DVE
