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.

Summary This study aims to analyze the buckling and post‐buckling behaviors of multilayer nanocomposite beams reinforced with graphene oxide powders (GOPs) at low concentrations. The GOPs are randomly oriented evenly distributed throughout composite layers, their weight fraction varying in thickness direction. Halpin‐Tsai model is employed estimate each layer's effective material properties. nonlinear governing equations for FG‐GOPRC beam derived based on first‐order shear deformation theory, a algebraic system formulated using principle potential energy. In this research, comprehensive parametric analysis conducted examine influence various factors beams. These include distribution pattern platelets (GPLs) nanofillers, as well geometry, size, slenderness ratio, boundary conditions Through analysis, highlights significant strengthening effect these performance findings from investigation contribute deeper understanding behavior GOPs. knowledge can be valuable designing optimizing structures enhanced resistance performance.
