What is tensile testing Instron?

A tensile testing machine performs the most fundamental and common types of mechanical testing. A tensile test applies tensile (pulling) force to a material and measures the specimen’s response to the stress. By doing this, tensile tests determine how strong a material is and how much it can elongate.

How do you use an Instron tensile tester?

  1. Step 1: Start the Computer and Machine. The order in which the computer and load frame are started is important.
  2. Step 2: Software Setup. a) Once inside the test method of choice, enter a sample name.
  3. Step 3: Loading the Specimen.
  4. Step 4: Equip the Extensometer (optional)
  5. Step 5: Starting the test.
  6. Step 6: Ending the Test.

How do you measure tensile strength of bioplastic at home?


  1. Tie a short length of your test material in a secure knot around the hook of the spring scale.
  2. Secure the top of the spring scale to something steady, like a table or wall.
  3. Pull on the test material until it breaks.
  4. Record the force measured by the spring scale right before the test material breaks.

How do you test the tensile strength of plastic?

Test Procedure:

  1. Cut or injection mold your material into one of the five. “dumbbell” shapes.
  2. Load the specimen into tensile grips.
  3. Attach the extensometer to the sample.
  4. Begin the test by separating the tensile grips at a constant rate of speed.
  5. End the test after sample break (rupture)

What is a load cell Instron?

Description. Instron load cells are an integral part of the load weighing system of a testing machine. The proprietary design, manufacturing and quality control are done with customer applications in mind. They are certified in accordance with international standards especially for use in materials testing machines.

What is Instron universal testing machine?

Universal testing machines include electromechanical and hydraulic systems to perform static testing, including tensile, compression, bend, peel, tear, shear, friction, puncture, and other mechanical tests. Universal Testing Systems up to 300 kN.

How do you determine tensile strength?

Tensile strength is defined as a stress that is measured as force per unit area. Typically, the testing involves taking a small sample with a fixed cross-sectional area, and then pulling it with a tensometer at a constant strain (change in gauge length divided by initial gauge length) rate until the sample breaks.

How do you measure the tensile strength of a material?

A tensile tester is used to measure tensile strength. A load cell is fitted to the tensile tester to measure tensile force. In addition a tensile test is commonly used to measure other properties of materials such as Young’s modulus of elasticity, yield stress, elongation, strain and ultimate tensile stress.

What is the tensile strength of plastic?

Typical Tensile Strength, Elongation, and Tensile Modulus of Polymers

Polymer Type Ultimate Tensile Strength (MPa) Tensile Modulus (GPa)
Polycarbonate 70 2.6
Polyethylene, HDPE 15 0.8
Polyethylene Terephthalate (PET) 55 2.7
Polyimide 85 2.5

What is the purpose of tensile testing?

Tensile testing is a destructive test process that provides information about the tensile strength, yield strength, and ductility of the metallic material. It measures the force required to break a composite or plastic specimen and the extent to which the specimen stretches or elongates to that breaking point.
