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

The ElectroForce 3300 family includes two models; the ElectroForce 3300 Series III instruments are well-suited for a variety of tests that include ASTM and ISO standards for materials and biomaterials characterization and long-term durability tests of materials, components and devices.
The ElectroForce 3300 family includes two models; the ElectroForce 3310 provides 1000 N of maximum force while the ElectroForce 3330 provides 3000 N. Both models are available with either table-top or floor-standing frames. The floor-standing frame enables the expansion of capabilities by either adding torsion or extended stroke motors. All configurations can perform tests that range from one cycle per day (or static tests) up to 100 Hz. Select the force capacity and frame configuration that is appropriate for your testing needs.
Key Features - High resolution and high accuracy displacement measurement for both the dynamic axial motor and the optional torsional motor
- Static to 100 Hz dynamic performance for a variety of applications
- Integrated System Status Indicator (SSI) Light for highly visible color-coded display of instrument status
- Electric motor driven test space adjustment with convenient locks, plus the added convenience of the lower Micro-adjust for precision alignment of grips.
- Optional 14 Nm and 25 Nm torsional motor are available for multi-axial test applications
- Optional 150 mm stroke extension motor to increase the instrument versatility for slower longer-travel tests
- Accommodates a variety of environmental chambers including temperature-controlled saline baths and hot/cold chambers
