What is Weak Form of IBVP in FEM about?

The document discusses the weak form of the initial boundary value problem (IBVP) and its significance in the Finite Element Method (FEM), highlighting that analytical solutions are often not possible. It explains the principles of virtual work and how they are applied to derive the weak formulation of the momentum balance and boundary conditions, which allows for approximation methods. The weak formulation is essential for FEM as it accommodates local errors during approximation while maintaining the integ
