## Stress Concentration Factors 2 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 2 Features:

- Calculates the Stress Concentration Factor
- Units in Metric and English Systems
- 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 2 calculates the stress concentration factors & displays the equations for 26 different geometries including:

Solutions:
   • Single U Notch in tension
   • Single U Notch in bending
   • Double U Notch in tension, bending, & out of plane bending
   • Single V Notch in bending
   • Infinite Row of U Notches in tension
   • Central Hole in tension
   • Central Hole in bending, & out of plane bending
   • Off Center Hole in tension & bending
   • Rectangular Hole in tension
   • Infinite Row of Holes in parallel & normal tension
   • Square Shoulder Fillet in Tension
   • Square Shoulder Fillet in Bending
   • U Notch Circular Shaft in tension
   • U Notch Circular Shaft bending & torsion
   • Stepped Circular Shaft in tension, bending, & torsion
   • Circular Shaft with a Radial Hole in tension, bending & torsion

### ***-- "Need References"
The app is easy to use. However, you need to include the source for the equations. In my work I need to verify the source of equations, otherwise it is just a black box.
