Test parameter compression strength

Introduction to test parameters:

In compression test, the maximum compressive stress that the specimen bears until it breaks (brittle material) or yields (non brittle material). Characterizes the ability of a material to resist compression without failure. Function and purpose of instrument:

It is used in the tensile, compression, bending and other conventional mechanical properties tests of various metal and non-metal materials.

Test basis: compression test method of metallic materials at room temperature GB / T 7314-2005

Test parameter compression yield strength

Introduction to test parameters:

In the process of material tension or compression, when the stress reaches a certain value, the stress increases slightly, but the strain increases sharply, which is called yield. The normal stress that makes the material yield is the yield stress of the material. When the metal material appears yield phenomenon, the compressive stress corresponding to the deformation of the specimen when the stress is no longer increased during the test process should be distinguished from the upper compressive yield strength and the lower compressive yield strength. Function and purpose of instrument:

It is used in the tensile, compression, bending and other conventional mechanical properties tests of various metal and non-metal materials.

Test parameter compression modulus of elasticity

Introduction to test parameters:

Elastic modulus E refers to the stress required by the material to produce unit elastic deformation under the action of external force. It is an index reflecting the ability of material to resist elastic deformation. The ratio of compressive stress to strain when the stress-strain relationship is linear. Function and purpose of instrument:

It is used in the tensile, compression, bending and other conventional mechanical properties tests of various metal and non-metal materials.
