Damping Responses of Viscoelastic Composite Material Structure Muhammad Iqbal Sabir 1, a , Guo Wan-Tao2, b , Liu Er-Bao 1, c, Li Li1, d,* 1 College of Materials Science & Chemical Engineering, Harbin Engineering University, China 2 LuoYang Ship Material Research Institute, LuoYang, China a iqbalsabir@hotmail.com, b guowantao@sohu.com, c liutong_05@163.com, d,* lili_heu@hrbeu.edu.cn Keywords: Composite materials, Viscoelastic, nonlinear Damping, Vibration Abstract: The work reported in this paper describes the behavior and prediction of damping properties of the 3D composite laminated engine mount shell structure.
Viscoelastic materials have been widely used for that purpose.
The continuous desire for materials having excellent properties, which would be light, stiff and have better damping characteristics have lead to consider composite materials not only from the point of view of how stiff or strong they are, but also from the point of view of how good a damping they can provide.
Experimental and analytical characterization of damping is not easy, even with conventional structural materials; and the orthotropic type of composite materials get even more complex.
This study presents that composite materials have the potential to use as engine or damping mounting devices.

Recycled rubber materials are one of cheap and suitable materials for energy absorbers in protective structures.
On the other hand, conceptual design focusing on overall concept of protection does not need precise and longtime lasting simulation but prefer time effective simplified simulation with trend of results for all main used materials.
The common feature for hyperelastic materials is fact, that typical compression is between 10 – 60% and the material curve for similar density materials does not differ significantly (see Fig. 1a).

The problem of an anti-plane crack situated in the interface of functionally graded piezoelectric materials (FGPMs) and homogeneous piezoelectric materials (HPMs) is considered under the impermeable assumption of crack surfaces.
However, for the interfacial crack problem of piezoelectric materials, some results have been reported.
Basic equations Fig. 1 shows the configuration of FGPMs bonded to HPMs denoted as materials 1 and 2, respectively.
