Tensile Testing Services
Impact Solutions provides tensile testing services for plastics and composite materials, helping manufacturers evaluate strength, flexibility, and performance under tension.
Our testing supports material selection, product development, quality control, and failure investigation.
What is Tensile Testing?
Tensile testing is a mechanical test used to determine how a material behaves when subjected to a pulling (tensile) force.
It measures a material’s ability to resist deformation and breaking, providing critical data on strength, stiffness, and ductility.
Why is Tensile Testing Important?
Tensile testing helps ensure materials will perform as expected under real-world loading conditions.
Key Benefits of Tensile Testing
- Determine material strength and durability
- Compare materials for design and specification
- Ensure compliance with industry standards
- Identify weaknesses before product failure
- Support quality assurance and failure analysis
How is Tensile Testing Performed?
Tensile testing is carried out by pulling a prepared specimen at a controlled rate until it deforms or breaks.
Typical Process
- Specimens are manufactured to standard dimensions (e.g. “dogbone” shape)
- The sample is mounted in a tensile testing machine
- A controlled force is applied until failure
- Stress and strain data are recorded throughout the test
Specimens can be prepared by injection moulding, compression moulding, extrusion, or taken directly from finished components.
Tensile Testing Standards
We perform tensile testing in accordance with recognised international standards, including:
- ASTM D638
- ISO 527
These standards define specimen geometry, testing conditions, and data interpretation methods to ensure consistent and comparable results.
What Properties are Measured in Tensile Testing?
Tensile testing provides a range of critical material properties:
- Tensile Strength – Maximum stress before failure
- Elongation at Yield – Extension at the yield point
- Elongation at Break – Extension at Fracture
- Strain at Break – Deformation at failure
- Modulus of Elasticity – Material stiffness (stress vs strain)
- Secant Modulus – Slope of the stress-strain curve
These properties are essential for understanding how materials will behave in service.
Advanced Tensile Testing Capabilities
We use a state-of-the-art Instron universal tensile testing machine to deliver accurate and repeatable results.
Our capabilities include:
- High-precision extensometers for accurate strain measurement
- Testing across a wide range of materials and specimen types
- Environmental testing using temperature-controlled chambers
- Sub-ambient conditions
- Elevated temperature testing
This allows us to simulate real-world operating environments and provide more meaningful performance data.
