BI-Axial Test System
The BI-Axial Test System is an advanced mechanical testing solution designed to perform simultaneous loading along two orthogonal axes. It is widely used in biomedical, composite material, and soft tissue mechanics research due to its ability to replicate real-world stress-strain conditions. This system is ideal for simulating planar deformation and evaluating anisotropic behavior in materials under biaxial loads.
Engineered for high precision and repeatability, the system supports both static and dynamic testing under controlled displacement or force modes. Its modular test frames and customizable grips accommodate a variety of specimens, from tissue samples to thin films and composite laminates. The system ensures accurate measurement of material behavior in critical research and OEM product development applications.
