Refined zigzag theory

Web2. máj 2003 · This paper gives a historical review of the theories that have been developed for the analysis of multilayered structures. Attention has been restricted to the so-called Zig-Zag theories, which describe a piecewise continuous displacement field in the plate thickness direction and fulfill interlaminar continuity of transverse stresses at each layer … WebOne class of refined theories that has emerged as practical for engineering applications is known as zigzag theories [12-24]. This class of theories employs a zigzag-like distribution for the in-plane displacements through the laminate thickness, while ensuring a fixed number of kinematic variables regardless of the number of material layers.
