Bi-Axial & Multi-Axial Testing Applications
What is biaxial materials testing?
Biaxial materials testing measures how materials respond to stresses applied in two perpendicular directions at the same time. This helps identify complex deformation and failure behaviors that can’t be seen in simple one-direction tests.
Why do people do biaxial materials testing?
People use biaxial testing to better understand how materials will perform under the complex loading found in cars, planes, medical devices, and other structures where forces don’t act in just one direction. Biaxial testing helps improve product design and safety.
What equipment is needed for biaxial materials testing?
Biaxial materials testing requires a biaxial test system that can apply controlled forces in four directions, often using actuators or motors. The setup also includes load cells, displacement or strain measurement systems, and specialized fixtures or grips to hold the specimen.
