THEORETICAL STRAINS 





Figure 11 - Theoretical and Measured Strain Sensitivities for Model OV-2 



Water was used as the pressurizing medium in the tests of Models 

 OV-1 and OV-2. They were tested to failure in a number of pressure 

 runs; the maximum pressures reached during each run were as follows:'
