The prime target of the present study is to inspect role surface elasticity at nanoscale in changing stability branches as well lower and upper limit loads uniformly thermomechanical loaded curved nanobeams having different degrees curvature. To this end, classical elastic-based multiple equilibria are predicted for nanosized third-order shear flexible clamped beams consisted through-thickness functionally graded porosity with schemes besides reinforcing by graphene nanofillers. established nanoscale-dependent nonlinear formulations then solved numerically aid isogeometric collocation technique creating a distinct grid points allocated contemplated basis assortments individually via Greville abscissas. It deduced that taking temperature escalation into account, along applied sidewise uniform pressure, prominence stress effects on quantity load reduces, while them enhances. These anticipations become more prominent FGP reinforced nanobeam possessing less degree Accordingly, owning small-curved nanobeam, increasing amount from 150°C 300°C, turns down 16.90% 1.51% if h=15nm, 6.76% 0.38% h=30nm, 2.48% 0.07% h=60nm.

Structures, Год журнала: 2024, Номер 63, С. 106431 - 106431

Опубликована: Апрель 21, 2024

This paper proposes a finite element model based on Quasi-3D theory, which includes both normal and shear effects, to study the bending, vibration, buckling responses of FG-CNTRC GPLRC curved beams. A two-node beam satisfying C1 continuity requirement is utilized compute displacements, critical loads, natural frequencies for beams with various boundary conditions. To evaluate precision suggested model, numerical examples are conducted. Next, comprehensive parameter carried out effects distribution patterns fractional volume reinforced materials, open angles, aspect ratios, Numerous results can serve as benchmarks subsequent investigations.
