### 1/5 — Calculation Error

*2014-02-11*

I used the single edge notched tension specimen using input values from textbook, Deformation and Fracture Mechanics of Engineering Materials, Hertzberg, and the stress intensity factor did not agree. 

The formulas for each specimen should be given.

### 4/5 — Stress Intensity factor

*2014-10-09*

It would be nice if this APP had the normal and shear stress equations to plug in the KI values (stress intensity factor) that are calculated on this APP release. Please make it happen?
