Abstract:

Some specificities of the construction of conservative finite difference schemas are discussed. The use of the finite difference discretization combined with the pseudoviscosity method allows one simulate the deformed state of multiply connected composite shells and plates with various cutouts on the groundwork of the nonlinear shear model of shells
