Abstract

For calculation of circular plates under bending, we used generalized equations of Finite difference method. The algorithm allows taking into consideration finite breaks of required function, her first derivative and the right part of the differential equation without using surrounding points and a special condensation of grid. The shown examples here illustrate the simplicity of the algorithm because the results obtained are satisfactory; compared to those of other researchers, the error is less than 5%.

Keywords

circular Plate, generalized equations, Finite difference method, edge conditions, discontinuity, finite breaks, surroundings points, convergence, constant loading.
