Prediction and Non-Destructive Buckling Test Method for Steel Cylindrical Shell under External Hydrostatic Pressure

This paper Analyzed buckling of steel cylinders in other researches. Here by using MATLAB software, a program to buckling pressure range of steel cylindrical shell under external pressure is provided. By comparing the output results and analysis charts, the risk of buckling in the cylinders can be detected with very good accuracy. After determining the proper correlation to predict buckling, hydrostatic pressure testing system with record pressure and volume changes for online registration prepared. In order to prevent suddenly destruction, buckling test equipment with volume control method has been prepared and the hydrostatic pressure tests were carried out on specimens of steel. So from overall load which make buckling will be prevented. By this method, prediction of buckling pressure and prevention of samples destruction can be done with about 16% error.
