H-DRILL is a specialized computer program for doing the stress
calculations for the popular hole-drilling method for measuring
residual stresses. Features of H-DRILL include:

•   Blind or through holes
•   Works with six common hole-drilling rosettes
•   Inch or metric units
•   Extensive data error checking
•   Not restricted to particular hole depths
•   Strain smoothing to get more stable stress solutions
•   Estimates ranges of stresses for given data uncertainties
•   Displays results in graphical and numerical formats
•   Uniform stress calculations according to ASTM E837-08
•   Stress vs. depth calculations according to ASTM E837-08
•   Power Series calculations for linearly varying stresses
•   Detailed instruction manual and answers to FAQ
