The structural performance and reliability of these sandwiches are dependent on the strength of the core-skin bonding.
The effects of various processing parameters on the core-skin bonding strength were investigated with parametric studies.
Moreover, effects of load height, gradual law, end-moment ratio and ceramic skin-core-skin thickness on the buckling capacity of a thin-walled FG open-section beam are also included in the analysis.
Effects of the boundary conditions, power-law index, span-to-depth ratio and skin-core-skin thickness ratios on the critical buckling loads and natural frequencies of the FG beams are discussed.
Finite element model (FEM) and Navier solutions are developed to determine the displacement and stresses of FG sandwich beams for various power-law index, skin-core-skin thickness ratios and boundary conditions.
Based on the developed theoretical mode, the influences of the FGM properties, gradient index, sandwich type, skin-core-skin ratios and porous material type on sound transmission loss are subsequently presented.
The composite materials with skin-core-skin structure are regarded as laminated orthogonal plywood and the elastic modulus, the shear modulus and Poisson's ratio are predicted under different slenderness ratios and fiber volume fractions.
Numerical results show that the fibers far away from the melt interface are in skin-core-skin structure, while those near the interface are almost parallel to the arc of the interface.
The structure and interfacial shear strength (IFSS) of polypropylene-glass fiber/carbon fiber hybrid composites fabricated by a new method called direct fiber feeding injection molding (DFFIM) process were investigated based on the skin-core-skin structure and modified Kelly-Tyson equation, respectively.
Numerical results are obtained for thin-walled FG beams with symmetric and mono-symmetric I-section and channel-section for various configurations such as boundary conditions, geometry, skin-core-skin ratios and power-law index to investigate the flexural torsional and lateral buckling loads and post-buckling responses.
