Damping can be divided into internal – the internal structure of material (kinetic energy is transformed to the thermal energy), contact – at the interface of two different environments, structural – participation of supports of the structure.

This is an electro active material whose electrical resistance changes with deformation.
These properties make this material suitable to develop force or deformation sensors [15,16].
The second is to change the gripper material, e.g. use stiffer silicone rubber, but it has to be carefully performed since too stiff a material leads away from a compliant mechanism with distributed compliance.

Microstructures and Creep Behavior of As-Cast TiAl-Nb Alloy Sugui Tian 1, a, Xiaoxia Wu1, Huichen Yu2, Haofang Sun1, Zehui Jiao2 1School of Materials Science and Engineering, Shenyang University of Technology, Shenyang 110870, China 2Beijing Institute of Aeronautical Materials, Beijing 100095, China Keywords: TiAl-Nb alloy, Microstructure, Creep, deformation mechanism, Fracture mechanism.
Introduction TiAl alloys have been widely investigated due to their excellent integrated mechanical properties [1], such as excellent strength, creep resistance and oxidation resistance at high temperatures [2]. the TiAl alloys are regarded as the better high-temperature structural materials with potential applications prospect for applying in aeronautics and astronautics field, they are expected to be used for making the hot parts in aero-engines to replace the high-density metal materials [3].
Compared to the ordinary TiAl alloys, TiAl-Nb alloy has better strength at high temperature and creep resistance, therefore, the one is thought to be the excellent high-temperature structural materials with potential applications prospect [4].
The creep resistance of the metal materials is related to their microstructure and deformation mechanism which includes the dislocations slipping and twinning deformation during creep [5].

WPC is used in the building materials [4,5], auto industry [6], furniture [7], logistics [8], packaging [9] and other industries with growing markets [3, 10, 11].
It is very necessary to consider many process parameters (thermal regulation, material flow rate, screw rotation speed etc.) which directly impact the material (temperature or flow rate changes, mechanical behavior evolution) [13].
The numerical simulation technique allows analyzing the material behavior inside the extruder.
