This lecture covers the Kirchhoff-Love Classical Plate theory, focusing on laminates made of thin plates. The theory's main assumptions include the use of plane stress approximation due to the finite thickness of the plates. It discusses the displacement vector components and the kinematic assumptions for plate bending. The lecture also explains the neglect of deflection dependence on the z-coordinate and the treatment of only bending problems. The strain components, stresses, curvatures, and equilibrium conditions are detailed, emphasizing the relationship between displacements and strains. The lecture concludes with the application of Hooke's law and the equilibrium conditions for moments applied to the plate.
