COMPUTERIZED TENSILE TESTING MACHINE

Read more

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)

  • Plastics & polymers

  • Rubber & elastomers

  • Wires, cables, fasteners

  • Composites and sheets

Standards supported

  • ASTM: A370, E8, D638, D412

  • ISO: 6892, 527

  • IS: 1608, 1828

  • BS / DIN standards (as required)

Key advantages

  • High accuracy and repeatability

  • Fully automated testing & reporting

  • Easy calibration and compliance

  • Suitable for R&D, QA/QC, and production labs

Optional features

  • Video extensometer

  • Temperature chamber (hot/cold testing)

  • Automatic hydraulic grips

  • Networked data storage

  • Customized test methods
