jännityskeskittymien
Jännityskeskittymien, a Finnish term often translated as stress concentration, refers to localized areas within a material where stress levels are significantly higher than the average stress applied to the object. These elevated stress regions typically occur at geometric discontinuities such as holes, notches, sharp corners, or changes in cross-section. When a load is applied to a structure, the material deforms, and at these points of abrupt change, the flow of stress lines is disrupted, leading to an accumulation of stress.
The presence of stress concentrations is a critical consideration in engineering design, particularly in the fields
Engineers use various methods to analyze and mitigate the effects of jännityskeskittymien. Finite element analysis (FEA)
