Einführung
A tensile testing machine is one of the most important instruments used to evaluate the mechanical behavior of materials under controlled tension. By stretching a specimen until deformation or failure occurs, tensile testing reveals critical information about strength, ductility, and elasticity.
In manufacturing, quality control, and research laboratories, tensile testing machines are essential for verifying material performance and ensuring compliance with international standards.
Tensile Testing Machine
A tensile testing machine applies a controlled tensile force to a material specimen and measures how it reacts under stress. The resulting data describes the material’s mechanical characteristics.
This test forms the foundation of material strength evaluation.
Definition of Tensile Testing Machine
A tensile testing machine is a mechanical or computerized device designed to determine tensile properties such as yield strength, ultimate tensile strength, and elongation.
It is often referred to as a universal testing machine due to its versatility.
Role of Tensile Testing in Material Science
