Selected Properties of FEM Numerical Models for Inverse Analysis of Road Pavement Structures
Wybrane cechy numerycznych modeli MES w analizie odwrotnej konstrukcji nawierzchni jezdni
Taking into consideration the key parameters of a finite element method (FEM) based pavement model, such as type, shape of mesh of finite elements, boundary conditions and dimensions, the authors compared the obtained values of elastic moduli with the results of calculations based on the classical theory of elastic layers positioned on elastic half-space (LET). The properties FEM model have been described for which the obtained difference between identified values of elastic moduli with respect to LET method is less than 10%. Moreover, in the majority of cases it has been concluded that the module of relative error of the values of elastic moduli identified with both methods depends on the depth of the layer within the model.
