Nyomásfeszültség

Nyomásfeszültség is a Hungarian term that translates to compressive stress in English. It refers to the internal forces that act within a material to resist compression or squeezing. When an external force is applied to an object in such a way that it tends to push parts of the object together, the object develops internal stresses to counteract this pushing force. These internal forces are called compressive stresses.

Compressive stress is a fundamental concept in solid mechanics and material science. It is measured in units of pressure, such as Pascals (Pa) or pounds per square inch (psi). Materials have a limit to how much compressive stress they can withstand before deforming permanently or fracturing. This limit is known as the compressive strength of the material.

Examples of compressive stress are common in everyday life. When you stand on the ground, your body exerts compressive stress on your legs and feet. Buildings and bridges are designed to withstand significant compressive stresses from the weight of their structures and any loads they carry. Concrete is a material that is particularly strong in compression, which is why it is widely used in construction.

Understanding nyomásfeszültség is crucial for engineers and designers to ensure the structural integrity and safety of various objects and constructions. By calculating and managing these stresses, they can prevent failures and create durable products.
