A Computerized Tensile Testing Machine (CTTM) is used to measure the mechanical properties of materials by applying a controlled tensile (pulling) load and recording the response digitally.

What it does

It determines properties such as:

• Tensile strength

• Yield strength

• Elongation (%)

• Reduction in area

• Young’s modulus (with extensometer)

All results are captured, displayed, and stored via computer-based data acquisition software.

Main components

1. Loading Frame

   • Rigid two- or four-column structure

   • Driven by servo motor / AC motor / hydraulic system

2. Grips & Fixtures

   • Wedge grips (manual or hydraulic)

   • Suitable for flat, round, wire, or threaded specimens

3. Load Cell

   • High-accuracy force measurement (typically Class 1 or better)

4. Crosshead & Drive System

   • Precise speed control for strain-rate–dependent tests

5. Extensometer (optional but recommended)

   • For accurate strain and modulus measurement

6. Computer & Testing Software

   • Real-time load–elongation / stress–strain curves

   • Automatic calculation of results

   • Report generation and data export

Typical capacities

• 1 kN – 100 kN → plastics, rubber, wires, thin metals

• 100 kN – 600 kN → structural steel, rebars, plates

• Higher capacities available in hydraulic models

Materials tested

• Metals (steel, aluminum, copper, rebars)
