It connects three layers that must be understood together: physical shell behavior, the [[Basic Shell Mathematical Model]], and finite element discretization. The paper focuses on thin-shell difficulty: as thickness decreases, shell problems split into bending-dominated, membrane-dominated, and mixed-dominated asymptotic behavior, and unreliable elements show [[Shell Locking Phenomenon]] in convergence curves.
