Visco-elastic material

When a satellite is in orbit, micro vibration generated by its actuators (such as reaction wheels, deployable mechanisms, etc.) will affect the imaging quality of the camera. Viscoelastic materials are utilized as passive isolators to reduce these micro vibrations due to their simple construction and excellent energy dissipation capacity.

The dissertation focuses on experimental evaluating the purely elastic and viscoelastic material parameters of proposed models via some standard experiments on relaxation, such as simple tension, pure shear and biaxial tensile tests. Both the isotropic and anisotropic materials were tested.
