Abstract Creep response of spherical shells under pressure is investigated to provide design guidelines to make the mathematical model applicable in engineering fields. In this study, creep deformation of the spherical shell is impacted by internal pressure and compressibility. Seth’s transition theory is adopted to derive the governing equations of creep deformation of the pressurized spherical shell without using the ad hoc assumptions of classical theory of deformation. Pressure required to initiate creep behaviour in the spherical shell made up of different thickness ratio is studied. Results are investigated theoretically and presented graphically. Keywords: creep stress, strain rates, spherical shell, pressure, compressibility, measure |
