PLASTIC ANALYSIS OF PRESSURE VESSEL INSTABILITY,

Abstract

Plasticity theory is used as a basis for analyzing the instability of pressure vessels for various ratios of biaxial stresses. Methods of analysis are developed which incorporate the behavior of the material with various degrees of precision. The methods are illustrated using Ladish D6AC. The predicted instability pressures are compared with the measured values. For the most precise method of analysis, predicted and measured values agree with 31/2% or better. The instability strains have a somewhat wider discrepancy. The analysis can be used as a design procedure to give an upper limit on the burst pressure. (Author)
