WebFeb 16, 2024 · To develop the finite element formulation, the partial differential equations must be restated in an integral form called the weak form. The weak form and strong form are equivalent. In stress analysis, the weak form is called the principle of virtual work. WebThe weak form of the PDE means that you have, in some sense, "fewer constraints on the kinds of functions that you can use" to construct a solution. To put it into perspective, recall that in FEM, you look for a solution of the form: ∑ j u j ∗ ϕ j ( x) can i sue for a hipaa violation
