This paper presents an innovative computational approach for modeling continuous material gradation in functionally graded sandwich beams (FGSBs) with porous cores, utilizing Ansys Mechanical APDL (Ansys Parametric Design Language). The properties of the FGSBs are modeled to vary progressively thickness direction based on a power-law distribution. uniform, symmetric, and asymmetric porosity patterns were examined assess impact different core configurations. meticulously using SOLID186 element, distribution rules explicitly coded via its tool. Two boundary conditions explored, namely clamped-clamped clamped-free, considering comprehensive three-dimensional representation beams. accuracy proposed was validated by comparing results free vibration, buckling, static bending analyses those from quasi-3D deformation theory-based finite element model, as well findings existing literature. An extensive parametric study delves into effects coefficient, distribution, skin-to-core ratio, index, slenderness, mechanical behavior FGSBs. study's demonstrate strong concordance literature, confirming precision reliability technique. validation paves way application various research areas involving FG structures across engineering disciplines.

Abstract In this study, a refined plate theory by considering stretching effects extended to investigation of quasi‐3D size‐dependent buckling analysis functionally graded simply supported nanoplate integrated with piezoelectric face‐sheets resting on orthotropic foundation taking into account the surface effects. The power law is used calculate material properties in core which non‐homogeneous are continuously changing along thickness. Due consideration materials and due asymmetry distribution core, middle plane neutral do not coincide. Hence, consider reference plane, concept considered. kinematics formulated nonlocal higher order shear deformation based strain gradient theory. Additionally, effect modeled piezo‐elasticity To check accuracy efficiency current model, comprehensive validation comparative study has been conducted results obtained found previous literature. Finally, investigate various parameters, including different foundations, residual stress, effects, effect, surface, aspect ratio, thickness nanlocal parameter, length scale index, initial voltage, examined critical load details. It expected that should be utilized designing micro/nano‐electro‐mechanical systems components smart nanostructures.
