In the current investigation, for first time, changes in limit loads and equilibrium branches associated with nonlinear in-plane stability characteristics of curved microbeams are explored presence different microstructural gradient tensors. this regard, multiple microsize-dependent equilibria analyzed relevant to thermomechanical loaded small-curved, medium-curved, large-curved made functionally graded porous (FGP) metal reinforced nanofillers possessing clamped end supports. To purpose, based upon strain elasticity within framework third-order shear flexible beam model, isogeometric collocation formulations incorporating Greville abscissae constructed resulting higher-continuity characters as well remarkable accuracy higher-order approximations. It is deduced that small-curved FGP microbeam, no load can be found due absence buckling phenomenon, but after rising temperature by an enough amount, initial instability mode appears. However, medium-curved occurs which results normalized upper equal 0.7161 on classical theory 0.7606 (6.21% enhancement). Also, it lower 0.3060 0.3521 (15.07% On other hand, bifurcation 1.0494 1.1358 (8.23% 0.2225 0.2513 (12.94%

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. While gets higher 48.69% 138.25% 22.70% 83.95% 8.89% 22.91% Owning medium-curved rise 14.98% 12.68% 7.09% 6.03% 2.84% 2.41% Alternatively, large-curved 22.30% 21.15% 10.38% 9.82% 4.11% 3.87%
