Tensile Testing
A Universal Testing Machine or Tensile Testing Machines is used to accurately measure the physical properties of solid materials.
A test system mainly consists of:
• Load frame of a suitable force capacity for the materials being tested
• Measuring transducers such as Load Cells to measure force and Extensometers to measure strain.
• Test fixturing or tensile grips to hold or support the specimen during the test
• Control and testing software to:
a. Enter dimensions and details of the specimen being tested
b. Control the Load Frame to follow a test profile such as a speed in units of mm/min
c. Measure calculations for Modulus, Peak Force, Elongation, and Poisson’s Ratio
d. Perform a statistical analysis of a sample batch tested
e. Export test data to network databases
• Temperature chamber for testing at hot or cold temperatures (optional)
Types of Test:
• Tensile Test - Modulus, Peak Force, Pre-Determined Preset Points, Break Point and Poisson’s Ratio
• Compression Test - Modulus, Peak Force, Pre-Determined Preset Points, and Break Point
• Bend Test - Modulus, Peak Load and Break Point
• Peel Test – Average Peel Force
• Tear Test – Tear Strength
• Shear Strength - Modulus, Peak Load and Break Point
• Coefficient of Friction – Static and Dynamic Coefficient of Friction
