CENTRAL DIFFERENCE METHOD APPLIED FOR THE BEAM RESTED ON NONLINEAR FOUNDATION (PROGRAMMING AND EVALUATION OF RESULTS)

Michenková Š., Frydrýšek K.
pages 421 - 424, full text

This work presents practical applications of experimental and numerical approaches in the solution of straight beams on elastic foundations. There are tangent-linear, nonlinear (i.e. linear + arcus tangent) and secant-linear approximations for dependencies of distributed reaction forces on deflection in the foundation. For solutions of nonlinear problems of mechanics, the Central Difference Method is applied in combination with the Newton Method. The results acquired by linear/nonlinear solutions are evaluated and compared.
