Strength

Dictionary

Impact strength describes the ability of a material to withstand impact loads or sudden forces without breaking or permanently deforming. It is usually determined using test methods such as the Charpy or Izod impact test, in which the energy that a material absorbs at break is measured. In the manufacturing industry, impact strength is decisive for the selection of materials in safety-relevant applications, such as vehicle components or machine components that are exposed to high mechanical loads. High impact strength ensures the reliability and durability of products under changing load conditions, which helps to reduce failures and increase safety.

Dictionary

Fatigue strength is the ability of a material to withstand repeated loading during operation without failure. It is calculated from the fatigue, the material properties and the real operating conditions. The fatigue strength can be predicted in advance using various tests and simulations. High fatigue strength has a positive effect on reliability and durability, which is particularly important in the automotive and aviation sectors as well as in mechanical engineering.

Dictionary

Yield strength describes the point at which a material remains permanently deformed. Once the material retains its elongation after the load is removed, the yield point is reached. The higher a material's yield strength, the more resistant it is to permanent deformation. Yield strength is usually measured in megapascals (MPa), and this is usually determined at the 0.2% yield strength (Rp 0.2), i.e., where the material has a permanent elongation of 0.2%.
