Refined zigzag theory
Web18. mar 2024 · The Refined Zigzag Theory (RZT) is used to formulate the corresponding governing differential equations (equilibrium/stability equations and boundary conditions). To solve these equations numerically, the recently developed Higher-Order Haar Wavelet Method (HOHWM) is used. 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.
