nyúlásmérk

The term "nyúlásmérk" is a Hungarian word that translates directly to "elongation gauge" or "strain gauge" in English. It refers to a sensor used to measure strain, which is the deformation of an object in response to stress. Essentially, a nyúlásmérk quantifies how much a material stretches or compresses under load.

These devices typically work by detecting changes in electrical resistance. A common type of nyúlásmérk consists of a thin, flexible backing with a metallic foil pattern etched onto it. When the material to which the nyúlásmérk is attached deforms, the foil pattern also stretches or compresses. This change in dimension alters the electrical resistance of the foil. By measuring this change in resistance, the strain can be precisely calculated.

Nyúlásmérők are employed in a wide variety of applications across numerous industries. They are crucial in engineering for testing the structural integrity of components, bridges, aircraft, and vehicles. In manufacturing, they are used for quality control and to monitor stress during production processes. Research and development also heavily rely on nyúlásmérők to understand material behavior under different conditions. Their ability to provide precise, real-time measurements makes them indispensable tools for understanding and quantifying mechanical deformation.
