Abstract

The paper points out a physical effect which enables constant-stresses biaxial-creep testing of thin-walled tubes and spheres. Uniform and isothermal expansion of tubes and spheres which are internally pressurized by a constant amount of an ideally behaving gas is followed by a reduction of the gas pressure. The pressure drop of the gas compensates for the dimensional changes of the vessels in such a way that the circumferential and axial stresses of tubes and the circumferential stresses of spheres remain constant.
