Breaking Strength refers to the maximum tensile or compressive force that a material can withstand before breaking under the action of a force. It is an important index to describe the strength and durability of materials. In material mechanics tests, the breaking strength is usually measured by applying a tensile or compressive force. The size of the breaking strength depends on the nature of the material, the preparation process and the test conditions. For engineering materials and components, fracture strength is one of the important parameters to evaluate their load-bearing capacity and durability, so it is of great significance to accurately test and evaluate them.

What is breaking strength?

The breaking strength is usually expressed as the unit area of force, i.e. N/mm² or psi. For metal materials, the breaking strength refers to the maximum stress that the material can withstand before breaking in a tensile test, often called tensile strength. For non-metallic materials, such as plastics, rubber, etc., the breaking strength is usually called tensile strength or tensile breaking strength, which is used to describe the maximum tensile stress that the material can withstand before breaking in the tensile test. In addition, there are some special test methods, such as impact test, bending test, shear test, etc., which can be used to measure the breaking strength of materials.

The fracture strength is important for the design and selection of materials. In practical applications, it is necessary to select suitable materials and processing technology according to specific application conditions, so as to ensure that the fracture strength of the material meets the requirements. In addition, proper quality control and testing is required to ensure that the materials produced have consistent performance and reliable quality.
