## Abstract A practical finite element method is presented for geometrically nonβlinear (von KΓ‘rmΓ‘n) plate problems. Symmetric strain energy tensors provide an efficient formulation and solution, and allow the effects of initial imperfections to be considered. An unbalanced force iteration is emplo
Existing solution techniques which are based upon the variational inequalities description of frictional contact problems mostly adopt penalty and regularization methods. The convergence and accuracy of these methods are governed by user defined parameters. To overcome the difficulties associated wi
