leikkaussäröä
Leikkaussäröä, also known as shear distortion or simply shear, is a type of deformation that occurs when a force is applied parallel to a surface of an object, causing layers of the object to slide past each other. This is distinct from tensile or compressive forces which act perpendicular to a surface. Imagine a deck of cards being pushed from the top; the cards slide relative to each other, demonstrating shear.
The effect of leikkaussäröä can be observed in various materials and situations. In engineering, it's crucial
In optics, the term can also refer to a phenomenon in laser resonators or other optical systems.
