| Abstract: | B-type measurement uncertainty evaluation was made for the strain measurement by gauges in the connecting region of spherical shell with large opening nozzle.It was found that the standard measurement uncertainty is generally less than 2% for the outside wall strain measurement,which can meet the need of stress experimental analysis. |
