What Test Can Be Performed on a Universal Testing Machine?

Materials’ compressive and tensile strengths can be evaluated with the help of universal testing machines (UTMs), sometimes known as universal testers. This battery of examinations may include standard tensile and compressive tests, seal strength and bond strength tests, and bend, pierce, and spring tests. 

A Universal Testing Machine consists of standard parts: a load frame to distribute the weight, a load cell to measure the applied force, an upper and lower crosshead to secure the product under test, an extension measurement mechanism, and a device to read the results. The sample of interest, the required capacity, and the necessity for environmental control conditions are all factors that should be considered when deciding on a machine to purchase.

What is UTM Machine?

Universal Testing Machine

To test the tensile and compressive strength of materials, a universal testing machine (UTM) is employed. This machine goes by several names, including UTM tester, materials testing device, and material testing frame. Tension, tensile force, compression, and transverse stresses are all examples of mechanical qualities. Each industry and sector have a distinct need for the capabilities and applications offered by universal testing machine manufacturer, and these machines are sold accordingly. UTM is a fantastic piece of multi-purpose machinery for use in quality control or research laboratories. 

UTM conducts several common tests, including:

  • Tensile Test: Materials’ tensile strength is measured by their ability to withstand tension and stretch before snapping in two when pulled from one end.
  • Compression Test: As indicated, compressive strength testing is the polar opposite of tensile strength testing, in which an object is stretched until it breaks. Any substance has this quality, known as compressive strength. Bridge piers, building beams, and other structural elements can all benefit from this test to determine their load capacities.
  • Adhesion test: Evaluates the adherence level of two substances.
  • Pull-out test: The force needed to remove a fastener or other embedded object from a material.
  • Bending test: Evaluates a material’s resistance to deformation when bent or flexed.
  • Hysteresis test: Calculates the amount of power a material loses as a result of being loaded and unloaded repeatedly

General Procedures

The load is transmitted hydraulically from the specimen under test to a remote load indicator. This approach is superior to others because it eliminates the use of levers and knife edges, which are vulnerable to damage from the shock generated by the rupturing of test pieces. A hydraulically lubricated ram is used to apply force.

The pendulum dynamometer system’s cylinder on the control panel receives pressure from the main cylinder. The dynamometer’s cylinder is self-lubricating as well. The force exerted on the test piece is proportional to the arc length of the pendulum’s swing. The energy released by the rapid shattering of the specimen is absorbed by the damping of the pendulum’s return motion.
