Abstract : Two designs of mini-hat pressure gages(G-X and J-1) were stress analyzed with three dimensional photoelasticity and a graphics-oriented, axisymetric finite element method. The results were compared with the exact theoretical solution of a pressurized cone. Both methods showed stresses higher than the theoretical solution in the central portion of the cone, and lower than the theoretical solution at the ends of the conical section. The J-1 gage showed a more linear distribution of the stress, in the conical section, than did the G-X gage. (Author)
