In this research, free vibration characteristics of functionally graded metal foam doubly curved panels reinforced with graphene platelets and porosities have been surveyed. Halpin Tsai's approach is utilized for extracting the effective Young modulus porous nanocomposite also density shell panel estimated by using an extended rule mixture. The FSDT hypothesis determining displacement field Finite element Hamilton principle are deriving mass stiffness matrices structure. Finally, influences several variables such as porosity distribution, coefficient, GPL dispersion pattern, weight fraction Nanofillers, span angles on vibrations FG platelet reported in detail.

The present research proposes an applicable and impressive analytical model of Aircraft Engine Cowl (AEC) due to auspicate its frequency parameter. For the first time, authors configured structure AEC by joining two well-known shapes shell, including elliptical conical. This procedure is implemented obtaining governing motion organization differential equations affiliated with Joined Elliptical-Conical Shells (JECS) in line first-order shear deformation theory (FSDT) General Shell Formulation (GSF). Moreover, Functionally Graded Materials (FGMs) various spreading forms along structure’s thickness are used enhance dynamic performance AEC. It worth mentioning that recognized Rule Mixture (RM) engaged for achieving equivalent mechanical characteristics FGM. Finally, a semi-analytical Generalized Differential Quadrature (GDQ) hired extract resulting system access free vibration responses diverse Boundary Conditions (BCs). interesting numerical done inspect remnants geometric material features on oscillation demeanor structures. will be verified projected can helpful AEC’s analysis extendable other types studies predict structure's static treatment.

This study addresses the issue of thermal stresses and strains in a thin-walled conical shell subjected to uniform heat flow along its side surfaces at both ends insulation shell. The governing equations are derived using semi-coupled static thermoelastic equation an energy equation. ignores strain rate effects, but behavior consider temperature variations axisymmetric shells. Semicoupled methods, due their simpler analysis, suitable for stress analysis when structural disturbances differ significantly. To obtain solutions, Galerkin finite element method is employed, yielding valuable insights. Using reduced weight residual method, sum residuals on thickness set zero. Through comprehensive problem-solving approach, effects increasing angle cone apex different boundary conditions investigated two one-ended two-ended cases.
