Title:  Model and bending analysis of sandwich beam with composite  facings and compressible orthotropic core using Abramov’s sweep method        Annotation Modern sandwich structures are employed in a broad range of aerospace, marine and civil structural applications. They are efficient and lightweight constructions with high bending stiffness, high strength, and high buckling resistance. Such modern sandwich structures are combination of composite facings with a lightweight core layer. The facings carry the tensile and compressive loads, while the core transmits shear loads and serves to hold the facings in positions, which maximize the flexural stiffness of the structure. Therefore, the general structural response of a sandwich structure is an action, consisting of couple, compression or tension stress resultants in the facings and shear stresses along with vertical normal stresses within the core. Note that, in such structures, the facings may undergo d...
