Uni-axial tension and compression testing are used to determine a number of important properties of a material or structure, including ultimate tensile strength, Young's modulus and yield strength. Uni-axial testing is typically used to evaluate isotropic materials (properties are the same in all directions) or when the operational load is always in the same direction of alignment with the material.
Zymetrix is equipped with four different machines for conducting uniaxial tension tests. All machines are from the Bose Electroforce Systems Group and use the Electroforce linear motors which have low friction and fidelity of control.

One of Zymetrix' core areas is in the mechanical characterization of biomaterials. As a Level 2 Biosafety facility, Zymetrix has performed testing on both animal and human tissues, including tensile testing of pericardium, vasculature, skin, tendon and ligament. Tensile testing of engineered biomaterials has included nitinol, collagen scaffolds and hydrogels. Our experience in compressive testing of biomaterials extends to bone, articular cartilage, tissue engineered cartilage, hydrogels and nanoparticles.
Our capacity for uniaxial testing is extended to industrial materials such as plastics, elastomers, composites, rubbers, fabrics, and adhesives.
