Abstract In this paper, we consider a viscoelastic von Karman equation with damping, delay, and source effects of variable exponent type. Firstly, show the global existence solution applying potential well method. Then, by making use perturbed energy method properties convex functions, derive general decay results for under more conditions relaxation function. General solutions equations nonlin...

Abstract. In this work, a Ritz formulation for the analysis of damage initiation and evolution in composite plates under progressive loading is presented. The proposed model assumes first order shear deformation theory considers geometric non-linearities through von Karman assumptions. modelled Continuum Damage Mechanics. A set results presented to show potential method highlight some issues be...

The current work concerns the study and the implementation of a modern algorithm for error estimation in CFD computations. This estimate involves the dealing of the adjoint argument. By solving the adjoint problem, it is possible to obtain important information about the transport of the error towards the quantity of interest. The aim is to apply for the first time this procedure into Petrov-Ga...

In this paper, the nonlinear vibration of functionally graded (FGM) cylindrical shells subjected to radial harmonic excitation is investigated. The nonlinear formulation is based on a Donnell’s nonlinear shallow-shell theory, in which the geometric nonlinearity takes the form of von Karman strains. The Lagrange equations of motion were obtained by an energy approach. In order to reduce the syst...

Nonlinear free vibration of stiffened functionally graded plates is presented by using the finite element method based on new C0 third-order shear deformation theory. The material properties are assumed to be in thickness direction a power-law distribution. Based Von Karman theory and theory, nonlinear governing equations motion derived from Hamilton’s principle. An iterative procedure Newton-R...

The repair of large distal femoral tumor defects can be challenging for orthopedic surgeons. The combination of a double-barrel free vascularized fibular graft (DFVFG) with a locking plate is a viable option. However, the biomechanical influence of the fibular bone length on the locking plate attachment is unclear. We aimed to evaluate the stability of the distal femoral defect after reconstruc...
