Grips/Fixtures

Overview

TA Instruments ElectroForce titanium tension/compression fatigue grips are low-mass grips that can be used in a variety of applications including engineered materials, biomaterials, and tissue testing.

In this mode, the sample is clamped at the top and bottom and placed in tension or tested ‘through zero’ for fatigue loading with reversing stress. Multiple tension clamps are available including a self-aligning and versatile wedge grip and a submersible vise grip with changeable faces.

Overview

TA Instruments ElectroForce platens are used for compression testing applications such as durability testing of components, or for dynamic characterization of viscoelastic materials. The platens have a lightweight, corrosion resistant design, making them well-suited for use on an ElectroForce test system or servo-pneumatic system.

In this mode, the sample is placed between upper and lower round plates and deformed by the instrument pushing the plates together. Different diameters of compression platens are available and can be used for a variety of materials and components where the properties and behavior in compression are critical and expected to be distinct from tension or bend.

Key Features

• Corrosion resistant design
• Can be used for both submersible and non-submersible applications
• Lightweight design
• Includes 10-32 UNF or 5/8-18 UNC or M16 mounting thread depending on platen size and applicable system
• Available platens include 10 mm, 25 mm, 50 mm, and 100 mm.

Overview

TA Instruments ElectroForce bend fixtures are often used to imitate real world conditions. Bending is particularly critical for layered materials where the shear stress is likely to introduce a delamination failure. The bending deformation mode creates unique stress states combining tensile and compressive stresses on the surfaces and shear stresses within the sample.

In this mode, the sample is deformed around three- or four-point contacts at both ends and near its middle. It is
considered a “pure” mode of deformation as the sample is freely supported by fulcrums eliminating clamping effects.
