Comparing the results of the welding residual stresses at outer surface of beryllium ring by FEM to that from X ray stress measurement, the stress trend is identical.
Conclutions the incorporated application of trend surface analysis and residual analysis could analyze the geographical characteristic of mortality rate level across-the-board.
