Is intended to assist designers in assessing the margin of safety in a pressure vessel by the use of stress analysis and a knowledge of the properties of the material of construction. The use of elastic analysis, limit analysis, shakedown analysis and elasto-plastic analysis are discussed particularly in reference to their application in BS 1515 and the ASME Pressure Vessel Code Section III. A list of references is included.Cross References:BS 1515:Part 1BS 3915ISO/R 831ASME Section III
