The vibration and buckling of sandwich cylindrical shells covered by different coatings subjected to the hydrostatic pressure

Thermal and thermomechanical postbuckling of FGM sandwich plates resting on elastic foundations with tangential edge constraints and temperature dependent properties

“…Recently, the vibration and buckling, and dynamic instability of FGM sandwich cylindrical shells subjected to uniform hydrostatic pressure and axial loadings have been analyzed by Sofiyev [35,36] basing on first order shear deformation shell theory. In above studies on FGM sandwich plates, with exception for works [25][26][27], main attention is focused on the bending and free vibration behavior and linear buckling of FGM sandwich plates loaded by mechanical compression without elastic foundation interaction and with temperature independent material properties.…”

Buckling analysis of freely-supported functionally graded truncated conical shells under external pressures

“…Based on the volume fraction definition and law of mixtures, the effective material properties of the FG truncated conical shells are defined as [14]: The shear stresses of FG conical shells in the framework of the STD vary depending on the thickness coordinate as [45][46][47][48][49][50]: …”

A global–local theory with stress recovery and a new post-processing technique for stress analysis of asymmetric orthotropic sandwich plates with single/dual cores

“…Although the three-dimensional elasticity approach and the layerwise theories (among them the zigzag theories) are known to lead to more accurate results, some well-known researchers have proven that accuracy of these theories may become less than that of the traditional theories [2,3], for very thin plates.…”

“…Since the thickness of the sandwich plates is often greater than that of the laminated composite plates and the transverse distribution of the material properties commonly experiences serious jumps at the interfaces between the layers, the traditional equivalent single layer (ESL) theories (the so-called global theories) such as the classical plate theory (CLT), first-order shear-deformation theory (FSDT), and even the higher-order shear-deformation theories (HOSDT) [2][3][4][5] may not lead to accurate results in many case, including cases wherein the core is fabricated from very soft materials or foams or number of the layers is large. Even separating the bending and shear components of the displacement may not improve the situation [6].…”
