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 Check out our other engineering apps by searching the App Store for: • Pressure Vessel Pro • Moments of Inertia • Mohr's Circle • Stress Intensity Factors Pro or search J.R.Hobbs to see them all.
