Stress coating is adopted in order to determine the points and directions of the most main stress of the frame, resistance straingauge method used for determining main stress value of the frame.
On basis of practice teaching, this paper introduced some obvious features and attentions and some technic problems when measuring pressure vessels stress with resistance straingauge.
