Numerical study on wavy interfaces

The interface between two solids is normally non-flat. The waviness of the interface introduces some new mechanical behaviours. In the present project, a numerical analysis via finite element method (FEM) is employed on the micro and macro models to study the elastic stiffness of the wavy interface...
