Fatigue

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

Resilience is the ability of a material to withstand stresses such as external forces or loads without failure. This property is of central importance in the manufacture and design of components, particularly in construction and mechanical engineering. The load limit of a material/component can be determined using various tests. The load limit varies depending on the physical properties of the material or the condition and processing of the component. A high load-bearing capacity is particularly important for safety and durability.

Dictionary

Impact resistance describes the strength of a material under sudden loads, such as hard blows or impacts. In various tests, such as the Charpy or Izod test, the impact resistance is determined by testing the material for sudden loads until it breaks or tears. High impact resistance is particularly important for applications with high dynamic loads. This is achieved by certain plastics or alloy steels, for example.

Dictionary

Magnetizability describes the ability of a material to develop its own magnetic properties under the influence of an external magnetic field. Materials such as iron, nickel and cobalt, some of which retain their magnetic properties even after the external magnetic field has been removed, are particularly suitable for this process. The magnetizability of a material is characterized by its permeability. High magnetizability makes materials particularly interesting for electrical engineering or magnetic bearings.

Dictionary

Viscosity describes the internal friction of a fluid and is a measure of its flowability. In the manufacturing industry, viscosity is crucial for processes such as casting, extrusion and coating, as it influences the behavior of materials during processing. Optimal viscosity ensures consistent production processes, improves the quality of end products and minimizes material losses. In addition, viscosity is important in the selection of lubricants and coolants to increase the efficiency and service life of machines. Accurate measurement and control of viscosity enables companies to precisely control their production processes and remain competitive.
