Why tensile testing is conducted?

Tensile testing is a destructive engineering and materials science test in which controlled stress is applied to a specimen until it completely fails.

This is one of the most common mechanical testing techniques used worldwide by engineers. This testing process is mandatory as it helps the engineer to understand a lot about the material. This form of testing is used to find out how strong a material is and how far it can stretch before breaking. This test method is used to determine yield strength, tensile strength, ductility, and work hardening properties. The tensile testing can be conducted by using a good quality tensile tester

Test characteristics

Profitability

The yield point is the point at which plastic deformation occurs under load. This is determined during the test over the measured length using a so-called extensometer. The device is either a mechanical clip-on device or a limited contactless video device. The test is conducted at a high temperature.

Tensile strength (UTS)

UTS is the maximum load applied to the specimen during testing. This may differ from the ultimate strength of the sample, depending on whether it has brittle, ductile, or both properties. These material properties can change due to environmental conditions such as extreme heat or cold.

Ductility

Ductility refers to elongation in tensile tests. Elongation is calculated by dividing the maximum gauge length by the original gauge length.

Stress concentration

How difficult it is to flesh out the plastic.

Modulus of elasticity

Young's modulus, also called Young's modulus, measures the stiffness of a specimen that allows the material to return to its original state when the stress is removed. When a material is stretched beyond its original length, then permanent deformation occurs in the material, and no longer can it bear its natural shape. This is called the elastic or proportional limit (also called the yield point).

Why are tensile tests performed?

Tensile testing provides information about the mechanical properties of materials. These properties can be plotted on graphs as stress-strain curves to show details such as the point at which the material fails, as well as properties such as Young's modulus, elongation, and yield strength.

Let us look at some of the benefits of tensile testing:

• Material selection for your application

• Predict how materials will behave under different forces

• Determining whether the requirements of a specification, contract, or standard have been met

• New product proof-of-concept demonstration

• Features of Proposed Patent Examination

• Providing standard quality assurance data for scientific and technical functions

• Comparison of technical data for different material options

• Material examination of the evidence for use in court proceedings

Types of Tensile testing

The type of tensile testing is usually determined by the type of material that is being tested. This type of testing can be broadly classified into 3.

• Adhesion/Peel/Bond Strength

• Crimp Joint Pull-off Force

• Tear Resistance
