Winkler-Pasternak Parameters C1 a C2

The Winkler - Pasternak model for the solution of an elastic layer introduces the balance equation in the vertical direction as:

where:

c1, c2

-

constants characterizing the Winkler - Pasternak model

w

-

displacement in the vertical direction

fz

-

vertical load acting on a layer

The elastic subsoil is introduced into the program using local stiffness matrices which are added to the stiffness matrices of individual elements resting on the subsoil. The contact stress σ is provided as an output.
