Modelling of contact interfaces using non-homogenous discrete elements to predict dynamical behaviour of assembled structures

The proposed new contact model is based on notion that the non-linear homogeneous definition of contact interfaces can be modelled with an equivalent local linearization and global non-homogeneous definition. Due to local linear elements, the model is computationally efficient and with non-homogeneous definition of contact stiffness and damping, the predominant effects of contacts can be captured.
