Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary element method based on these integral equations, and its implementation for the shell problem are discussed in detail. A 'tangent stiffness' iterative procedure is used to obtain the nonlinear solution. Numerical results are presented to demonstrate the efficiency and the accuracy by the present approach.
