INTEGRATED PHOTOELASTIC
FRINGE PATTERN
If the thickness of the model is comparable with its other ACKNOWLEDGMENT
dimensions, we are close to the Boussinesq problem. In this
The author is thankful to Leo Ainola for discussion. The sup-
case the real axial stress is calculated as
port of the Estonian Science Foundation under Grant No.
