Discrete-Continual Finite Element Method for Semianalytical Analysis of Plates on Two-Parameter Elastic Foundation.Part 2: Discrete-Continual Formulation of the Problem,Numerical Samples

摘要

This paper is devoted to application of discrete-continual finite element method(DCFEM)for semianalytical solution of problems of analysis of plates on two-parameter elastic foundation.Corresponding resultant multipoint boundary problem for system of ordinary differential equations of the first order with piecewise-constant coefficients is presented.Numerous samples of problems of structural mechanics have been considered.These samples allow demonstration of some advantages of application of the suggested approach to semianalytical analysis of plates on elastic foundation.
