in this article, the bending and free vibration analysis of functionally graded (fg) nanocomposites timoshenko beam model reinforced by single-walled boron nitride nanotube (swbnnt) using micro-mechanical approach embedded in an elastic medium is studied. the modified coupled stress (mcst) and nonlocal elasticity theories are developed to take into account the size-dependent effect. the mechani...

The study presents the investigation of elastic behavior soil in optimal design continuous foundations according to rigid solid case. For investigation, optimization algorithm that can find section and reinforcement details has been developed. developed uses one well-known meta-heuristic methods named artificial Bee Colony method design. Winkler spring hypothesis (analytic solution) is used cal...

In the present paper, a novel unconstrained higher-order theory (UCHOT) is applied to analyse free vibration of cylindrical sandwich shells with nanocomposite face sheets reinforced graphene platelets. UCHOT considers shear and thickness deformations. It assumed that cylinder includes soft core which embedded between functionally graded platelets composites (FG-GPLRC). FG-GPLRC sheet consists s...

Suction caisson foundations provide options for new foundation systems offshore structures, particularly wind turbine applications. During the design process, it is necessary to make reliable predictions of stiffness foundation, since this has an important influence on dynamic performance overall support structure. The characteristics structure, in turn, its fatigue life. This paper describes a...

in the current study, an effort is made to determine three dimensional bearing capacity of rectangular foundations using discrete element method. the soil mass is modeled as discrete blocks connected with winkler springs. different factors affect the geometry of failure surface. six independent angles are used to define the failure surface. by trial and error, the optimum shape of failure surfa...

in present study, thermo-elastic buckling analysis of multi-layer orthotropic annular/circular graphene sheets is investigated based on eringen’s theory. the moderately thick and also thick nano-plates are considered. using the non-local first and third order shear deformation theories, the governing equations are derived. the van der waals interaction between the layers is simulated for multi-...
