The following article investigates nonlinear symmetric buckling of moderately thick circular Nano plates with an orthotropic property under uniform radial compressive in-plane mechanical load. Taking into account Eringen nonlocal elasticity theory, principle of virtual work, first order shear deformation plate theory (FSDT) and nonlinear Von-Karman strains, the governing equations are obtained ...

Various problems involving the interaction of water waves with thin plates are reduced to hypersingular boundary integral equations. Examples include scattering by submerged curved plates and by surface-piercing plates, in two dimensions; trapping of waves by submerged plates; and scattering by submerged flat plates in three dimensions. Each integral equation is solved numerically, using an exp...

An inexpensive video densitometer based on an Apple II microcomputer using commercially available components was developed. The device was used to quantitate charred lipid and colored spots on thin-layer chromatography plates. The method is useful for lipid samples weighing 0.1 to 4 micrograms on high-performance plates and 1 to 20 micrograms on ordinary plates. The software automatically corre...

Large-amplitude, geometrically non-linear vibrations of free-edge circular plates with geometric imper-fections are addressed in this work. The dynamic analog of the von Kármán equations for thin plates, with a stress-free initial deflection, is used to derive the imperfect plate equations of motion. An expansion onto the eigenmode basis of the perfect plate allows discretization of the equatio...
