THEORY, EXPERIMENT AND NUMERICAL APPROACH FOR THE BEAM RESTED ON NONLINEAR ELASTIC FOUNDATION

Frydrýšek K., Michenková Š.
pages 177 - 180, full text

This work presents theory, approximations of experiments and numerical approaches suitable for the solution of straight plane beams rested on an elastic (Winkler's) foundation. The nonlinear dependence of the reaction force can be described via bilateral tangent-linear or secant-linear or nonlinear (linear + arcus tangent) approximations. These applications lead to linear or nonlinear differential equations of 4th-order (Central Difference Method, Newton-Raphson Method).
