The joints are associated to the local non-linear behaviour, while the material properties are associated to the global behaviour. This paper presents an approach to model - the dry contact interfaces using localized non-homogenous discrete elements and the material behaviour of composite structures using equivalent classical laminate technique. A prototype structure of an Electronic Control Unit (ECU) is used to validate the proposed model's capability in predicting the dynamic behaviour, wherein the global damping is assimilation of contact and material damping.
