| Abstract: | The boundary conditions for solving viscoelastic vibration differential equation are given,from the differential equation of viscoelastic vibrations of the ice sheet.The numerical solution of the partial differential equations is derived,based on the basic theory of the finite element numerical solution of partial differential equations in combination with Bubnov-Galerkin method.By an example calculation,deflection characteristics of the ice sheet are given under the vibration load. |
