Sometimes simple stress formulae are not enough. The real peak stresses in hardware occurs at geometric discontinuities such as notches, holes, & filets. To get an accurate stress value, you need a stress concentration factor. This app makes that easy. Along with stress concentration factors, this app calculates the nominal and peak stresses, displays the equations, & easily prints or shares via email your result with a couple of taps.

Stress Concentration Factors Pro Features:

✓ Calculates the Stress Concentration Factor
✓ Nominal Stress
✓ Peak Stress
✓ Designed for use on the iPhone, iPod Touch, & iPad
✓ Printing Capability
✓ Ability to email a PDF of the Geometry, Inputs, Equations, & Results

Stress Concentration Factors Pro calculates the stress concentration factors & displays the equations for 26 different geometries including:
