The discontinuity stresses in the vicinity of discrete supports welded to the hemispherical end of a pressure vessel under internal pressure have been measured. Four brackets fabricated from flat plates and three tubular supports were examined. Experimental stresses compared reasonably well with stresses estimated by approximate analytical methods which are suggested as standard design checks.
