Understanding Stress Contrations
Stress concentrations concelers whens a sudden change ion the geometri of a component, leading to localized readses in stress. Theese changes cae bune due tree toe varouos factors, including:
- Notches and keyways
- Changes is cross- sectionala area
- Holes and cuttout
- Material properties
