The tensile strength of any product whether it is paper, plastic, or heavy materials like iron or steel, plays a key role in improving the lifecycle of that particular product. The tensile strength of any product primarily depends on the material and its intended force or load.

To determine this strength and the maximum load that a material can withstand, you need a tensile testing machine, also known as a tensile strength tester. In engineering terms, the tensile stress of a material is measured by the ratio of the magnitude of applied force to the cross-sectional area.

What Is Tensile Strength or Tensile Stress

Tensile strength is a material’s ability to resist the pulling force or force against tension before it starts breaking. In other words, it is the maximum force that a material can bear when it is stretched or pulled. Needless to say, it is a very important material property in engineering applications as it assists in finding the best material for a product.

Example – Hold a piece of paper in between both of your hands and pull it in the opposite direction. Your pulling force is the tensile force and when it crosses a certain threshold (of paper), the paper will tear. Similarly, you may have seen thick wires used in suspension bridges which is also a prominent example of tensile strength.

How is Tensile strength measured?

The material’s tensile strength is measured through a tensile testing machine. A specimen (sample piece) is gripped between both ends of the machine and constantly increasing tensile force is implemented till the specimen gets fractured.

At the point of maximum load when the material is fractured, is noted and the corresponding length is measured to find the cross-sectional area of the tested specimen. The more the tensile strength of the material, the better it will be for the required application.

It must be noted that if a tensile load or tensile stress is applied to a material, its atoms undergo dislocation motion. Dislocation is the process by which atoms are moved out of their usual positions, which causes deformation and, eventually, breakdown.

Why Need a Tensile Testing Machine?

Tensile strength testing is a crucial phase of product development in every industry. When developing a new product or making improvements to existing products, finding the best suitable material is a must. In general, and engineering industries, Tensile strength tester has the following major applications:

  • Automotive Industry – Excessively used to measure the strength and durability of mechanical components like brake pads and suspension systems.
  • Construction Industry – The safety of buildings and bridges depends on the materials used in construction. By measuring the tensile strength of the material, engineers ensure the utmost safety.
  • Medical Industry – A tensile strength tester is crucial to measure medical equipment like lenses, surgical tubes, needles, bandages, etc.
  • Packaging & Paper Industry – To measure the force required to tear a seal, adhesive bond, labels, etc.
  • Aerospace Industry – The use of tensile testing machines is paramount in the aerospace industry. The wings and nose of an Aeroplan confront rigorous air pressure and tensile force. Also, the strength of cables, gaskets, hoses, seat belts, wiring looms, etc needs to be measured.

Top 3 Tensile Testing Machines You Can Refer

A tensile strength tester, also known Universal testing machine (UTM), consists of a load frame, load cell, grips, crossheads, software like an extensometer, and control system. Before purchasing a tensile tester, you must know the purpose of the tester, the type of material, and how much load capacity is required for your product or material. In general purpose, the following three would be your best companion –
