In this study buckling analysis of solid rectangular plate made of porous material in undrained condition is investigated. The mechanical properties of plate are assumed to vary through the thickness direction. Distributing of the pores through the plate thickness are assumed to be the nonlinear nonsymmetric, nonlinear symmetric, and monotonous distribution. The effect of pores and pores distri...
Free vibration and wave analysis of thick rectangular graphene are studied by employing the propagation method. To consider small-scale effects thickness a plate in nanoscales, equations motions represented Eringen nonlocal theory coupled with Mindlin plates. solve governing motion technique, reflection matrices derived. These combined to obtain exact natural frequencies sheets for all six poss...
Abstract : In this research, active control of vibrations of a simply supported rectangular plate is investigated by a new method. At first, differential equation of motion of a plate with piezoelectric patches is developed by means of classical plate theory in order to apply in this method, and a local function is used for applying the mass and stiffness effects. Then, natural frequencies an...
High voltage electron microscopic tomography was used to determine the organization of the kinetochore plate and its attachment to the underlying chromosome. Six reconstructions were computed from thick sections of Colcemid-treated PtK1 cells and analyzed by a number of computer graphics methods including extensive thin slicing, three-dimensional masking, and volume rendering. When viewed en-fa...
