Re: [PSUBS-MAILIST] FEA Work on Acrylic CT for KLH-500

Brent,

This is why I suggested doing some comparison tests against known data 
in Stachiw's book. Replicating the t/D data points of .045 that Stachiw 
recorded with actual testing (page 754) would give some credence that 
you've got the program configured correctly.
