Tensile Testing: Learn All About It

Tensile testing is a mechanical test used to determine the strength and durability of a material by subjecting it to tension until it reaches its breaking point. Learn more about it below.

Tension testing or Tensile testing is one of the most common mechanical tests performed to examine the physical properties of the material’s specimen to produce a better final product. 

As we all know, Quality is an essential factor in determining a product’s standard. Therefore every industry must excel at this to reach more customers. On this page, you will read about tensile testing, its significance, industry standards, and procedure. 

 Please continue reading to learn more about it.

What Is Tensile Testing? 

Tensile testing

To begin with, Tensile testing is a mechanical test used to evaluate a material’s strength, flexibility, and other mechanical properties. In this type of product quality test, a material sample is subjected to controlled tension until it breaks or deforms. This facilitates comprehending how the material will behave under various loading conditions. 

A tensile test, for example, can be used to determine the strength of a metal bar or the elasticity of a rubber band. Then the lab test results can be used to determine the suitability of a material for a specific application and to design structures that can withstand the stresses that will be applied to them.

Why Is Tensile Testing Important? 

Tensile testing is an essential process for determining the strength and behavior of materials under various loads. It is widely used in the engineering, manufacturing, and construction industries to check material quality and dependability. Tensile testing helps define a material’s maximum load capacity, deformation under different loads, and breaking point. This information is significant in designing and constructing structures and products that withstand the expected loads and stresses.

For example, it is used in the construction sector to test the strength and durability of building and overpass materials. In contrast, it is used in the manufacturing industry to test the quality of raw materials used to produce products such as car parts and airplane components. Tensile testing data empowers engineers and manufacturers to select suitable materials and design structures and products that can perform well under varying loads, ensuring their safety and reliability.

What Are The Testing Standards For Tensile Testing? 

After getting familiar with tensile testing and its significance, let’s move forward and have a look at some of the essential standards that need to be considered for tensile testing. 

  • ASTM E8/E8M

This standard specifies the test specimen size, device calibration, test protocols, and data analysis for tensile testing on metallic materials.

  •  ISO 6892-1

This standard describes preparing test specimens, calibrating test equipment, and analyzing test results while performing tensile tests on metallic materials at room temperature.

  • ASTM D638

About testing specimen size, machine calibration, test protocols, and data analysis, this standard offers instructions for performing tensile tests on plastic materials.

  • ISO 527-1

This standard offers instructions on preparing test specimens, calibrating test apparatus, and analyzing test results when performing tensile tests on plastic materials.

  • ASTM A370

Concerning test specimen measurements, equipment calibration, test protocols, and data analysis, this standard offers instructions for performing tensile tests on steel items.

  • ISO 6892-2

This standard outlines the procedure for specimen preparation, test instrument calibration, and data analysis for conducting tensile tests on metallic substances at high temperatures.

Industries, including aerospace, automotive, and construction, frequently employ these testing standards to assure precision and uniformity in tensile testing.

What Is The Complete Procedure Of Tensile Testing? 

Now that you know the standards that need to be considered for tensile testing let’s understand its procedure. 

Step 1: Preparing The Sample

Begin with choosing test-appropriate material. A consistent cross-sectional surface, gauge length, and gripping space should be provided for the sample, which should also be manufactured following the applicable requirements. Ensure the piece is free of flaws or inconsistencies that could taint the test outcome.

Step 2: Installing The Sample

Ensure the sample is upright and centered before inserting it into the testing device’s grips. For the gauge length of the piece, the grips should be modified to the proper distance.

Step 3: Calibration

The testing device should be calibrated before the test to measure precisely. Making the required modifications entails evaluating the load cell and displacement measurement modules.

Step 4: Pre-test Preparation

Before performing the test, you must write down the sample’s specifications, including the gauge length and beginning cross-sectional surface. Take note of the testing temperature and other relevant environmental factors like moisture and air pressure.

Step 5: Pre-test Measurements

Before beginning the test, take the sample’s actual gauge length readings.

Step 6: Start The Test

Start the test by putting a tensile strain on the sample that increases progressively until it cracks. Based on the material being examined, the force is applied steadily, ranging from 2 to 20 millimeters per minute. The device keeps track of the sample’s extension or strain throughout the test and the applied force.

Step 7: Post-test Measurements

Measure the ultimate gauge length and the shattered ends’ measurements after the sample cracks.

Step 8: Data Analysis

Using the test results, determine the engineering load, engineering strain, and other pertinent characteristics, including Young’s modulus, yield strength, and maximum tensile strength. Remember that based on the standard adopted and the substance being tested. These estimates may change.

Step 9: Interpretation of results

Consider the test findings to assess the material’s mechanical characteristics and decide whether it is suitable for a range of applications.

Step 10: Reporting

Record the test outcomes and create a thorough report that includes the test’s specifications, sample preparation and measurements, calibration, test circumstances, results produced, and charts and tables if necessary.

That gives a broad description of the tensile testing process. It’s essential to remember that the methods and calculations employed may differ slightly between standards.
