pingutusperioodide
Pingutusperioodide is a term used in materials science to describe sets of dynamic loading cycles defined by alternating periods of elevated strain or stress and relaxation. The word combines Estonian roots pingutus ('strain, tension') and perioodide ('periods'), and the plural form denotes multiple cycles within a test or simulation. In English-language literature, the exact term is not widely standardized, and related concepts are usually described under broader headings such as dynamic loading or cyclic loading.
In practice, a pingutusperiood may consist of a rapid rise to a peak strain, a short plateau,
Applications and methods: They appear in fatigue testing of metals and polymers, vibro-mechanical analysis, and biomechanical
Measurement and interpretation: Experimental data come from strain gauges, extensometers, or digital image correlation; results are
