Yield point?

The yield strength is the stress at which a material exhibits a defined permanent elongation. It is measured in megapascals (MPa) or newtons per square millimeter (N/mm²) and determined by tensile tests. In this test, a material sample is loaded until a visible permanent deformation occurs.

Significance of the yield point for the construction

For engineers, knowledge of the yield strength is crucial to ensure that components do not suffer permanent deformation under the expected loads. It serves as a basis for the calculation of safety factors and the selection of suitable materials for specific applications.

Factors influencing the yield point

The yield strength of a material is influenced by various factors, including the type of material, the temperature, the rate of loading and the environmental conditions. These parameters must be taken into account when selecting materials and designing to ensure the reliability and durability of the components.

Practical applications and importance in the industry

The yield strength is used in a variety of industrial applications, such as vehicle construction, aerospace technology, power generation and the mechanical engineering industry. It helps engineers to dimension components so that they can withstand dynamic loads and environmental conditions.

Consideration of the yield strength when selecting the material

When selecting materials for technical applications, the yield strength is a decisive criterion. High-strength steels, aluminum alloys and titanium alloys are examples of materials with high yield strength that are preferred for demanding applications.
