Tensile Testing

It is a fundamental materials science test in which a sample is subjected to a controlled tension until failure.

The results are used to select a material for an application, for quality control, and to predict how a material will react under other types of forces.

Properties directly measured via a tensile test are Yield Strength, Proof Stress, Ultimate Tensile Strength, % Elongation and % Reduction in area.

Hardness Testing

The property of a material that enables it to resist plastic deformation, usually by penetration, is referred to as hardness.

Hardness is a measure of the resistance of a material to surface indentation or abrasion.

There is no absolute scale for hardness; each type of test has its own arbitrarily defined scale, making it one of the most common and widely used tests across engineering fields.

Wide range of materials can be tested with available different hardness testers

Impact Test

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture.

This absorbed energy is a measure of a given material's notch toughness and is used to study temperature-dependent ductile-brittle transition.

Impact resistance is one of the most important properties for a part designer to consider, and is a critical measure of service life.
