Book excerpt: An evaluation is undertaken of currently used discretization procedures in numerical analysis of structures. Emphasis is on the nonlinear behavior of thin shells and plates. It is found that the computer economy is extremely sensitive to the choice of element configuration. A proper balance between the order of the approximations of inplane and lateral displacements is important. The best finite element procedures are superior to finite differences for bifurcation buckling and for moderate nonlinearity. However, for shell collapse analysis the finite differences approach is quite superior to the finite elements. Suggestions are made for improvement of finite element technology for structures undergoing large rotations.
