Working Principle
The Steel Strand Tensile Testing Machine clamps the steel strand specimen securely using dedicated wedge grips. A servo-driven or electro-hydraulic loading system applies tensile force at a controlled rate while maintaining stable loading throughout the test.
During testing, the load cell continuously measures force, while the displacement system records specimen elongation. The intelligent software automatically analyzes the data and calculates:
* Ultimate Tensile Strength (UTS)
* Yield Strength
* Maximum Load
* Elongation
* Breaking Force
* Elastic Modulus (optional)
The complete testing process is displayed in real time, and professional reports are generated automatically.
