In the present exploration, unconventional tensors of nonlocal stress and couple are incorporated simultaneously in in-plane nonlinear stability analysis functionally graded (FG) multilayer shallow micro/nano-arches under thermomechanical loading conditions. For this purpose, (NCS) mechanics continuum is implemented into third-order shear flexible arch theory incorporating von Karman kinematical nonlinearity. The nanocomposite material FG reinforced with graphene nanofillers accordance different patterns lamination. generalized differential quadrature numerical strategy conjunction pseudo arc-length continuation procedure employed to deduce roles NCS-based paths loaded micro/nano-arches. It found that for all lamination, contributions associated nonlocality small scale effects on value upper limit as well first bifurcation compressive loads less than those lower second ones. Also, it demonstrated by combining a temperature rise applied lateral load, load increases, while one decreases. Furthermore, seen applying rise, an initial deflection induced micro/nano-arch before load.

There is a diverse and well-constructed application of energy harvesting systems due to their innovate technology provide the necessary power for low-energy electronics. In this regard, prime objective current study analyze size-dependent nonlinear dynamic performance piezoelectric beam-type harvesters at nanoscale subjected time-dependent mechanical uniform load. A laminated structure containing an agglomerated nanocomposite core integrated with top bottom surface layers considered bridge-type harvesters. To take size dependency into account, nonlocal strain gradient continuum elasticity formulated based upon quasi-3D beam theory incorporating both features effects. Thereafter, problem then solved numerically relevant simply supported clamped end conditions via employing meshless collocation technique. Accordingly, numerical solving procedure established without any background meshes as well eliminating integration singularity by using proper multiquadric radial basis functions.

This paper comprehensively investigates the electro-induced nonlinear static bending and vibration behaviors of graphene platelets reinforced dielectric porous (GPLRDP) arches. The effective permittivity Young's modulus GPLRDP composites are determined based on medium theory (EMT). governing equations for arch under electrical voltage derived by using Hamilton principle numerically solved utilizing differential quadrature method (DQM) together with an iterative scheme to obtain its dynamic responses. influences porosity, GPL concentration, boundary condition, central angle, DC AC discussed in detail. It is found that addition GPLs has significant effects mechanical GPLRDC when weight fraction exceeds percolation threshold. Numerical analysis proves can be designed actively tuned through adjusting material structural parameters, providing valuable insights development smart
