Abstract It is becoming increasingly necessary to obtain data on the biaxial-stress behavior of many materials. One of the most commonly employed methods of obtaining this information, over a wide range of stress ratios, consists of subjecting thin-walled tubes to various combinations of internal pressure and independent axial load. Some of the problems associated with this method of testing are discussed, together with a description of how they may be overcome in order to apply pressures of up to 20,000 psi and axial loads of 35,000 lb. A new method is presented for producing conditions of constant-mean-stress ratio which takes into account the changing dimensions of the specimens. The results presented are the first that have been obtained on the plastic instability behavior of thin-walled tubes deforming under constant-ratio biaxial stress. They suggest a cautious approach to some of the best known work on biaxial-fracture phenomena.
