Did you know that biomaterials deform depending on the direction of the applied force? IRS is pleased to present BioMechTest: a system to measure the deformation of soft tissues and evaluate their mechanical properties. Thanks to the biaxial planar configuration, biaxial tensile stresses can be measured.

BioMechTest is specially designed and configured to meet customer-specific sample sizes and test conditions. The machine controls: four synchronised actuators, four load cells for force measurement, four encoders for displacement measurement and a camera with 100 frames per second for detailed evaluation of deformation over the entire sample surface.

What is the purpose of a planar biaxial test?

Biomaterials can be subjected to various stress-strain conditions when in use. The response of materials, especially biomaterials, also depends on the direction of stress (anisotropy), so a specific biaxial test is necessary to get a correct measure of the mechanical properties.

Planar biaxial tests determine the mechanical properties of the test specimen undergoing biaxial tensile stress states and can also be used for modelling purposes. Planar biaxial test data are superior to uniaxial test data if the material is stressed in complex multiaxial configurations during its service life. Biaxial tensile strength, compressive strength, flexural strength, fracture properties and fatigue life can be determined for a material using a planar biaxial test.

What materials are used in planar biaxial tests?

The most common planar biaxial tests are performed on soft biological tissues, fibrous soft tissues, metal sheets and plates, hard foams, hyper-realistic rubber, composite laminates, thin films, fibre-reinforced polymer composites, silicone elastomers, textiles, flexible materials and rigid substrates. Testing of biological soft tissue is common in the biomedical industry.

BioMechTest is designed specifically for soft materials and biological tissues. It explores the performance of biomaterials through stress fatigue and flexural tests over time.
