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.
