Abstract: The mechanical model of viscous pressure bulging process is presented. The viscous pressure bulging process of hemispherical sphere is analyzed by the numerical simulation and experiments. The research results show that the viscosity of viscous medium significantly affected the thickness distribution, strain distribution and shape of hemispherical sphere, which provides analytic basis for selecting reasonably viscous medium and designing process of viscous pressure forming.
