In the present study, a spectral finite element method is developed for free and forced transverse vibration of Levy-type moderately thick rectangular orthotropic plates based on first-order shear deformation theory. Levy solution assumption was used to convert the two-dimensional problem into a one-dimensional problem. In the first step, the governing out-of-plane differential equations are tr...

Abstract A quadrilateral flat-shell element is developed for analysing the deflections, stresses and natural frequencies along with their allied mode shapes of cylindrical, spherical, conical shell panels made up layered composite sandwich material. The (DKZigTS1) based on zigzag theory has seven local as well global DOF per node. concept obtaining transformation matrix used transforming action...

Liquid food can likely cause accidental ingestion in patients with dysphagia. This study proposes a handheld stirrer-type rotational viscometer that be used the kitchen or at meals for A novel is proposed considering rotation speed of stirrer inversely proportional to viscosity fluids stirred. We adopt sensorless control strategy. use small brush-type DC motor, which functions as rotary actuato...
