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