Elastizitätsmodul

Elastizitätsmodul, also known as Young's modulus, is a fundamental material property that describes its stiffness or resistance to elastic deformation under tensile or compressive stress. It is defined as the ratio of stress to strain in the elastic region of a material's behavior. Stress is the force applied per unit area, while strain is the relative change in length or shape. A high Elastizitätsmodul indicates a stiff material that deforms little under load, while a low value signifies a more flexible material.

This modulus is crucial in engineering design and material science for predicting how a material will behave under various mechanical loads. It is an intrinsic property of a material, meaning it is independent of the object's size or shape and depends primarily on the material's composition and microscopic structure. Different materials have vastly different Elastizitätsmodul values; for instance, steel has a much higher modulus than rubber. The unit of Elastizitätsmodul in the International System of Units (SI) is the pascal (Pa), or more commonly, gigapascals (GPa). Understanding this property helps engineers select appropriate materials for applications ranging from bridge construction to microelectronics.
