Abstract:
The displacement fundamental equations of the thick shallow shells and thick cylindrical shallow shells concerning five independent variables, ie five middle surface displacements were established based on the displacement fundamental equations of the thick shells by transverse shearing deformation and basic hypothesis on shallow shells. Authors analyzed thick cylindrical shallow shells' dynamic characteristics by introducing three assistant displacement functions, ie authors converted five second-order differential equations into a second-order differential equation and two fourth-order transition differential equations using Cauchy-Riemann condition, and then introduced another assistant displacement functions to build its decoupled governing differential equations and obtained five displacement components through four assistant displacement functions. The displacements of equations of thick shallow shells degenerate to the displacement equations of the thick cylindrical shallow shells and thin cylindrical shallow shells, which are proved to be right and demonstrate the generality of derived equations.
