App Description
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:
