This article discusses the dynamic computation of the closed cylindrical shell underimpact load.In the text we analyse the changes of the momenta and the energy
In this paper,on the basis of the incremental Reissner variational principle.a nonlinearfinite element analysis has been accomplished and a formulation of hybri
A mixed variational formulation for lage deformation analysis of plates is introduced.In this formulation the equilibrium and compatibility equations are satisf
