Shear test
The shear test checks a material's resistance to parallel shifting. It determines shear strength and deformation behavior under shear loading.
Physical-chemical Mechanism of Action
A shear test measures how much force is required to slide two parallel surfaces of a material against each other. This is done by applying loads to the surface of the material, and the material is then sheared until it suddenly breaks.
Metallurgical Relevance & Risks in Welding
Shear strength is critical for the hardness and stability of components under shear load. A shear test value that is too low can lead to cracks or deformation, which is especially relevant in stress fields like chains or bands.
Workshop Practice & Instructions
To perform the shear test, the material is clamped in a special testing device and sheared. The force required to break the material is measured. A typical shear test value for steel is about 150 to 200 MPa. If values are insufficient, check the material properties or the manufacturing process.
