Description
Summary:On the basis of the moment scheme, the resolving relations of the method of finite elements in the actual configuration were obtain to be used used for the computer simulation of the processes of shaping of spatial shells by using a single finite element across the thickness. The reliability of numerical results is checked by the solution of a test example of shaping of a long narrow rectangular membrane. As an illustration of the possibilities of the developed approach to the analysis of the processes of shaping of thin-walled products with complicated shape, the results of numerical simulation of strains in a blank made of D16 alloy in a discrete press tool are presented.
