Generalized DAlembert-Lagranges principle for non-holonomic mechanics, including its Newtons formulation and Lagrangian formulation, are given. This principle can lead to the closed motion equations.
Based on the updated Lagrangian description, the incremental equilibrium equations of triangular plate shell elements for geometrically nonlinear problem are derived.
