Finite Elements for the Problems of Shock Load and Nonstationary Deformation of the Composite Shells and Plates

To study numerically the problems of shock load and nonstationary deformation, we propose some modified finite elements for the multilayer fibrous laminated composite shells and plates, which account for transversal shears, normal squeezing, rotational inertia, and the viscoelastic behavior of the material. We state the requirements on the finite elements of this type, determine the domain of their use, and make a comparative analysis of the convergence and precision.
