In this paper,the nonlinear axial symmetric deformation problem of nonhomogeneousring-and stringer-stiffened shells is first solved by the exact analytic method
This paper presents analytical solutions to the partial differential equations forunsteady flow of the second-order fluid and Maxwell fluid in tube by using the
In this paper.each of the two phases in dense two-phase flow is considered ascontinuous medium and the fimdamental equations for two-phase flow are described in
