DEFORMATION AND THERMAL BEHAVIOUR OF TRAPEZOIDAL CORRUGATED COMPOSITE SKINS

. In this research the ultimate deflection and strain in the trapezoidal corrugated composite sheets are considered as experimental. The anisotropic behavior of the trapezoidal corrugated composite sheets made of glass/epoxy is studied using both theoretical and experimental approaches. Two parameters, E*, and D*are defined. According to the both experimental and theoretical results, corrugated composites have high extremely anisotropic behavior and high ultimate strain in the longitudinal direction. Finally, deformation of the trapezoidal corrugated composite sheets under thermal loading is investigated using ABAQUS package. Thermal deformation and thermal expansion coefficient in longitudinal directions of the corrugated sheets are extracted theoretically. Generally, the thermal expansion coefficients for corrugated and flat sheets are equal in transverse and longitudinal directions of the corrugation.
