摘要：
The main objective of the present research work is to develop a computational model to simulate the visco-elastic dynamic contact problems. The proposed mathematical model exploits the incremental convex programming in the framework of a finite element model. The main concern of the model is to study basically the effect of the internal material viscosity on the dynamic characteristics of the system such as rate of decaying and response amplitude. Rayleigh damping model is adopted for simulating the internal material viscosity. For model verification and testing two examples of different natures are solved.
