چکیده:

During the manufacturing process and operating conditions of multilayered fiber-reinforced quasi- Trapezoidal corrugated composites with variable fiber orientations, residual stresses build up due to the directional expansion of the unidirectionally reinforced single layers. Depending on the properties of skin, these inhomogeneous residual stresses, which are primarily caused by thermal effects, can lead to out-of-plane displacement in the unsymmetric laminates. Instead of avoiding laminates curvatures, they can be advantageously used for technical applications such as morphing structures. In this research, parameters such as geometry and dimensions of corrugation made of Graphite/Epoxy are investigated and simulated by commercial FEM software, Marc Mentat
