# STRESS CONCENTRATION FACTOR CALCULATORS

**Stress Concentration Factors Calculators**
have been developed to calculate theoretical stress
concentration factors (K_{t}) in
elastic range for
different type of stress raisers and loading conditions (tension,
bending and torsion).

Dimensional changes and discontinuities of a member in a loaded structure causes variations of stress and high stresses concentrate near these dimensional changes. This situation of high stresses near dimensional changes and discontinuities of a member (holes, sharp corners, cracks etc.) is called stress concentration. The ratio of peak stress near stress riser to average stress over
the member is called stress concentration factor.
