microstrain (suomeksi)

Määritelmät:

(lb, en, physics) A strain expressed in terms of parts per million
(lb, en, materials science) The root mean square of the variations in the lattice parameters across the individual crystallites, usually across microscopic distances, <ϵ²>^1/2. By definition, it cannot be negative. In contrast, macrostrain refers to the overall change in the lattice parameters caused by a composition change or temperature change or pressure change.
