Tensile Testing Machine Fundamentals and Explanations

tensile testing

Tensile testing, that is completed with the help of tensile testing machine, is a damaging testing technique. A sample is held in two grips by a tensile strength tester, who later smears a tensile load that increases until the specimen breaks. The tensile strength is proficient of computed when the specimen’s unique cross-section and rate of elongation—or the rate at which its distance alterations are known. The regular cost of Tensile Testing Machine India ranges around between INR 25000.00 – 125000.00 INR.

What Is a Tensile Testing Machine?

A machine used to amount a material’s motorized possessions is called a tensile testing machine. A tensile test machine carries a tensile load to an exam component until it fails using either an electromechanical and hydraulic mechanism. The rate of elongation, applied load and length change will all be recorded by the tensile strength machine throughout the test, and these data can be utilized to ascertain the specimen’s material qualities. 

What Advantages Do Tensile Testing Machines Offer?

Understanding the characteristics and behaviors of a variety of materials is made possible using a tensile test machine. 

Tensile testing has additional advantages that allow you to:

  • Test the material’s quality
  • Determine any material flaws
  • Determine design flaws
  • Locate fresh materials to employ in a product
  • Certify a component or substance for a novel use

What make up the components of a Tensile Testing Machine?

A tensile test machine consists of a metal load frame with a moving as well as a static crosshead which is used to pull apart a test item with two specimen grips. 

The components of a tensile test machine are:

  • A load cell
  • Specimen Grips 
  • Extensometer
  • Moving Crosshead 
  • Load Frame
  • Electronics 
  • Data Acquisition System 

How Do You Operate a Tensile Testing Device?

Grasping a specimen with a known cross-section, a tensile tester pulls it apart at a set speed until it breaks. Tensile strength, stiffness and elongation can all be determined by interpreting the results of the tensile test. A lot of tensile testers are also capable of compression. The setup happens to be the same for a compressive test, however the material is held in place using various grips and the action is in reverse. 

Tensile Testing Machine Applications

Ultimate tensile strength, Yield strength, and ductileness are among the mechanical characteristics of a material which could be determined with the help of tensile test equipment. 

Kind of Tensile Testing Machines

Tensile testing equipment come in two primary varieties, which are detailed below:

1. Hydraulic Tensile Testing Machines

A hydraulic tensile test machine is an apparatus that applies a tensile load on a test specimen to ascertain its qualities. It does this by means of a hydraulic system. A single or dual-acting piston which applies a significant force to the specimen using Pascal’s law is the foundation of hydraulic tensile testers. 

2. Electromechanical Tensile Testing Machines

An electromechanical tensile tester applies the necessary tensile load for a test using a motor with speeds that vary. Textiles, elastomers, composites, and polymers are all tested by these electromechanical test machines.

How Do I Operate a Tensile Testing Device?

An operator loads a specimen into the machine’s two specimen grips to conduct a tensile test. The operator chooses the appropriate rate of movement for the material type upon loading the specimen. After that, the tester disassembles the specimen until it breaks. The extensometer shall electronically plot the movement on a graph while recording the distance travelled. After finished, the graphic findings are evaluated to comprehend the material’s characteristics and behavior.

Conclusion

For academia and manufacturers across all industries, tensile testing and material analysis are essential. Tensile testing is a mechanical testing method used to assess the tensile characteristics of materials and goods. It is carried out on universal testing machines. To ascertain the characteristics and behaviors of a material, a tensile test machine is essential. To choose the best materials for a particular purpose, tensile tests must be performed to ascertain mechanical qualities.
