A composite plate is a type of plate made from layers of different materials, typically fibers and matrix, which are combined to achieve specific properties. The fibers, such as carbon or glass, provide strength and stiffness, while the matrix, such as epoxy or polyurethane, binds the fibers together and provides additional properties like toughness and corrosion resistance. The layers of a composite plate can be oriented in different directions to achieve desired properties, such as increased strength, stiffness, or thermal resistance. % Define laminate properties n_layers = 4; layers

FEA is a numerical method that discretizes the plate into smaller elements and solves the equations of motion for each element. FEA can handle complex geometries, nonlinear material behavior, and large deformations. However, FEA requires a high degree of expertise and can be computationally expensive.
