Stress Concentration Review
Apply a user-entered theoretical stress concentration factor to nominal stress and show the local elastic stress proxy.

WHAT THIS SCREEN ANSWERS
Shoulders, holes, keyways, threads, and notches can concentrate stress far above a nominal section result. The page applies a user-entered theoretical factor to a stated nominal stress without inventing a geometry value. Treat the result as a checkpoint in the load path rather than a verdict.
Fatigue response also depends on notch sensitivity, surface finish, size, residual stress, material, and load ratio. Confirm actual geometry, source for Kt, fatigue method, surface condition, load history, and material data. Its effect belongs in the next comparison.
Shoulders, holes, keyways, threads, and notches can concentrate stress far above a nominal section result. Fatigue response also depends on notch sensitivity, surface finish, size, residual stress, material, and load ratio. Record any value that is inferred, estimated, or still awaiting measurement.
The page applies a user-entered theoretical factor to a stated nominal stress without inventing a geometry value. Confirm actual geometry, source for Kt, fatigue method, surface condition, load history, and material data. The decision remains specific to this application because shoulders, holes, keyways, threads, and notches can concentrate stress far above a nominal section result. Turn the remaining unknowns into a short verification list.
