This lecture covers the Kirchhoff-Love Classical Plate theory, focusing on laminates made of thin plates. The theory assumes finite plate thickness, leading to plane stress approximation. It discusses displacement components and kinematic assumptions, neglecting extensions along the mid-plane. The lecture also explains the theory's basis on Euler assumptions for beams, emphasizing kinematic assumptions and equilibrium conditions. It delves into strain components, stresses determination, and curvatures caused by applied moments. The equilibrium between applied and internal moments is crucial, with a detailed explanation of the stiffness matrix and curvature vector. The content is essential for understanding plate bending problems and structural mechanics.
