Tear resistance (or tear strength) is a measure of how well a material can withstand the effects of tearing. [1] It is a useful engineering measurement for a wide variety of materials by many different test methods .
The tear test (e.g. Kahn tear test) provides a semi-quantitative measure of toughness in terms of tear resistance. This type of test requires a smaller specimen, and can, therefore, be used for a wider range of product forms. The tear test can also be used for very ductile aluminium alloys (e.g. 1100, 3003), where linear elastic fracture ...
Materials can be characterized by standard test methods to measure their tear resistance. There are several applicable standards which vary around the world. The variables which affect tear strength are defined "the shape of the test piece, speed of stretching and temperature." [1]
Textile testing is the process of measuring the properties and performance of textile materials—textile testing includes physical and chemical testing of raw materials to finished products. Textile testing assists textile production in selecting various types of fibers and their transformation into yarn , fabric, and finished goods such as ...
Tearing strength is the ability of the paper to withstand any tearing force without break. It is useful to evaluate web runability, controlling the quality of newsprint and characterizing the toughness of packaging paper. Tear strength for paper is measured in units of force, frequently measured with the Elmendorf Tester.

The most common is the Charpy impact test, which uses a pendulum hammer (striker) to strike a horizontal notched specimen. The height of its subsequent swing-through is used to determine the energy absorbed during fracture. The Izod impact strength test uses a circular notched vertical specimen in a cantilever configuration. Charpy testing is ...
