The nonlocal nonlinear buckling of a double layer graphene sheet (DLGS) covered by zinc oxide (ZnO) piezoelectric layers is investigated in this study. The surrounding circumstances of the system are considered as a Pasternak foundation including spring constants and a shear layer. Graphene sheets are subjected to longitudinal magnetic field and biaxial forces. On the other hand, the ZnO piezoe...

Abstract In this article, we deal with a strongly damped von Karman equation variable exponent source and memory effects. We investigate blow-up results of solutions three levels initial energy such as non-positive energy, certain positive high energy. Furthermore, estimate not only the upper bound but also lower time.

In the presented paper, the governing equations of a vibratory beam with moderately large deflection are derived using the first order shear deformation theory. The beam is homogenous, isotropic and it is subjected to the dynamic transverse and axial loads. The kinematic of the problem is according to the Von-Karman strain-displacement relations and the Hook's law is used as the constitutive eq...

In this paper a general analytical solution is obtained to find stress distribution in a finite elastic plate with a circular or square hole subjected to arbitrary biaxial partial loading using modified boundary condition by assuming plane stress conditions. The method employed is based on solution of circular hole in finite rectangular plate. This plate is mapped to circular ones and the parti...

We perform numerical expe riments wit h a novel cellularautomaton fluid mod el. T he mod el has simple pair -in t eraction rules and works in arb it rarily man y dimensions; here we consider the twodimension al case . By observing the smoothing-out of the velocity profile of a shear flow and t he relax ati on of a shea r wave, we measure t he kin em ati c shear viscosity and obtain a value of R...

This paper undertakes a study of behavior solutions corresponding to von Karman thermoelastic plates involving nonlinear source. It is well-known that the source term gives rise finite-time blow-up and drives system possible instability. So, it interest explore mechanism dissipation. In this paper, on one hand, for low initial energy, we apply modified potential well method differential inequal...
