Stress Concentration Factors 2 vs Structural Engineering Suite

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.

Structural Engineer Hub is a complete structural engineering platform that combines professional calculators, animated simulators, a full learning curriculum, and field assessment tools in one app. Whether you're an engineering student mastering statics and steel design, a practicing engineer running a quick beam check on site, or an inspector documenting a structure's condition, Structural Engineer Hub puts the essentials in your pocket — and it works offline. The app is organized into two modules. Buy only what you need, or get both in a discounted bundle. STRUCTURAL ENGINEER'S TOOLKIT • Beam calculator — UDL, point, and off-center loads • Column calculator — Euler buckling + yield • Structure assessment for houses, bridges, buildings, and walls • ASCE 7-22 load combination generator • Full SI ↔ Imperial unit converter • Digital inspection checklist with scoring • Camera capture for condition documentation • Sample problems and a materials library STRUCTURAL LEARNING STUDIO • 7-module structured curriculum • 8 animated simulators (beam, column, seismic, wind, and more) • LRFD / ACI / ASCE 7 Quick Calc Hub • Guided projects with step-by-step instructions • Drawing gallery of structural illustrations • Searchable reference library • Lesson bookmarks, personal notes, and progress tracking WHY YOU'LL USE IT • Works offline — no account, no internet required • One-time purchases — no subscriptions, ever • Buy a single module or unlock everything with the bundle • Grounded in ASCE 7, AISC, and ACI engineering standards • Built for real engineering work, from the classroom to the field From study to site, Structural Engineer Hub is the structural toolkit you'll actually keep on your phone.
