väsymisrasituksen
Väsymisrasitus, known in English as cumulative fatigue or fatigue loading, refers to the detrimental effects on materials and structures caused by repeated application of stress cycles over time. This phenomenon is distinct from static failure, where a single overload causes immediate breakage. Instead, väsymisrasitus involves gradual damage accumulation within a material.
The process of väsymisrasitus begins with microscopic cracks forming at stress concentration points, such as surface
The severity of väsymisrasitus is influenced by several factors. The magnitude of the applied stress is crucial;
Väsymisrasitus is a critical consideration in the design and maintenance of many engineering structures and components,
