Choose from electromechanical, electrodynamic and servohydraulic systems


Planar biaxial test machines are increasing in popularity because of their unique ability to generate in-plane stresses that replicate multiaxial real-world stress states. Each planar biaxial system includes four actuators mounted opposite of each other on two axes with each actuator independently controlled by a four-channel servo controller that ensures independent and synchronized control of motion, strain or load. Each actuator is controlled to work with the other three actuators to replicate desired biaxial stresses.

Our planar biaxial test systems can be configured with contacting extensometers or a suitably configured DIC (digital image correlation) video camera, which makes strain measurement control possible. The majority of our applications are best served with all-electric actuators. Servohydraulic actuators are recommended for very high loads and for demanding fatigue testing applications. However, if your application requires relatively low forces and your tests are quasi-static or below 15 Hz, then electromechanical and electrodynamic actuators tend to be favored compared to servohydraulics.

Start by Selecting a Series

Low force biaxial test applications are suited to the 574 series electrodynamic tester, which is used in mechanical, biomedical, and materials engineering research. You can use this all electric dynamic modular test machine for applications such as hard foam, glass fabrics, textiles, sheet metal fastening, silicone elastomer, orthotropic plates and biological samples such as fibrous tissues, arterial walls, back disc tissues, skin, and heart valves. They are ideal for testing the mechanical properties of directionally oriented microstructures.

High force biaxial tests are commonly served by our 174 and 974 series test machines. The 174 includes an electromechanical actuator that can produce loads up to 200 kN (45,000 lbf) and quasi-static speeds up to 2 Hz. The 974 servohydraulic systems are used for higher forces and tests speeds. Test sample types include sheet metal, metal plate, aluminum alloys, composite laminates, fibre reinforced polymer composites, plate girders, cell core sandwich materials and reinforced concrete.
