Tensile testing is the most fundamental mechanical analysis used to determine how a material or component behaves under axial tension. By applying a controlled “pull” until the specimen reaches its breaking point or a predetermined load limit, TRI systems establish a high-resolution profile of material strength, stiffness, and ductility.
The Mechanics of Tension: Key Performance Metrics
TRI systems are engineered to provide the precision data required by R&D engineers and quality control professionals. Their equipment delivers accurate measurements for:
- Ultimate Tensile Strength (UTS): The maximum stress the material withstands before failure.
- Yield Strength: The critical point where a material transitions from elastic (temporary) to plastic (permanent) deformation.
- Modulus of Elasticity: A measure of the material’s inherent stiffness and its ability to resist deformation.
- Elongation & Ductility: Analysis of how much a material stretches before it snaps, essential for safety-critical components.
TestResources System Series & Frame Selection
TestResources manufactures a diverse range of load frames to suit different material types and force requirements:
- 100 Series: Designed for low-force applications (up to 2,250 lbf) such as thin films, medical packaging, and fine wires.
- 200 Series: Engineered for high-elongation materials like elastomers and polymers that require extended crosshead travel.
- 300 & 600 Series: High-capacity workhorses for metals, structural composites, and heavy-duty industrial components, scaling from 1,125 lbf to 500 kN+.
Modular Interface & System Integration
To maximize laboratory uptime, TRI frames utilize a standardized hardware logic:
- Standard Interface: For applications up to 20 kN (4,500 lbf), TRI utilizes a standardized 16mm (16M/16F) mounting interface. This allows for rapid transitions between various wedge grips, pneumatic grips, and specialized fixtures.
- Newton Controller: All frames are powered by the Newton Controller, providing synchronized, high-speed data acquisition of both load and strain.
- Extensometer Support: Our systems feature strain channels, allowing for the integration of clip-on extensometers or video extensometry to meet the highest accuracy standards for modulus calculation.
Common Standards Supported
TRI equipment is designed to execute protocols in strict accordance with international standards, including ASTM D638, ASTM E8/E8M, ISO 527, and ASTM D412.
