Dynamic Characteristics of Cross-Ply Laminated Shells

Optimization of a Two Joint Cross-Ply Laminated Conical Shells to Minimize the Natural Frequencies

This study deals with the vibrational behavior of two joined cross-ply laminated conical shells. Natural frequencies and mode shapes are investigated. Joined conical shells can be considered as a general case for joined cylindrical-conical shells, joined cylinderplates or cone-plates, cylindrical and conical shells with stepped thicknesses and also annular plates. Governing equations are obtain...

Multiscale Analysis of Transverse Cracking in Cross-Ply Laminated Beams Using the Layerwise Theory

A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...

Bending Response of Cross-Ply Laminated Composite Plates with Diagonally Perturbed Localized Interfacial Degeneration

A laminated composite plate element with an interface description is developed using the finite element approach to investigate the bending performance of two-layer cross-ply laminated composite plates in presence of a diagonally perturbed localized interfacial degeneration between laminae. The stiffness of the laminate is expressed through the assembly of the stiffnesses of lamina sub-elements...

Improved Smeared and Zigzag Third-order Theories for Piezoelectric Angle-ply Laminated Cylindrical Shells under Electrothermomechanical Loads

Non-destructive Characterization of Ply Orientation and Ply Type of Carbon Fiber Reinforced Laminated Composites

As the fuel efficiency of vehicles is being increased over the next decade due to both consumer demand and regulations, several automobile manufacturers are incorporating fiber-reinforced composites into their product line due to their high strength to weight ratio. While the fiber-reinforced components are lighter than the traditional aluminum and steel components, the processing and repair of...
