Finite Element Modelling

All foundation models shown foregoing lead to the same differential equation. Basically, all these models are equivalent and differ only in the definition of its parameters [6].

The various two-parameter elastic foundation models define the reactive pressure of the foundation \(p(x)\), as [6]

(1)\[p(x) = kw(x) - t\frac{d^2w(x)}{dx^2}\]
