[SlideRule]

An extract from The Use of Acoustic Emission to Determine the Integrity of Large Hybrid Packages, US Dept. of Comm., NBS-NEL, NBSIR 80-2055, JUN 1980, 41 pgs.

* A program for calculating eq (1) (fixed boundary conditions) appropriate to hand-held calculators using inverse polish notation is included in the appendix, since this is the boundary condition most used for PC boards in avionics equipment. A similar program for eq (2) is available on request to the author.
