This paper sets up a simplified physical model for viscoelastic pipe, on which a investigation on energy dissipation mechanism of it is presented and some new conclusions are given.

Furthermore, the intrinsic mechanism of energy dissipation during the deformation and fracture of rocks can be disclosed by the research of meso damage mechanics.

Studies are made in the article on the mechanism of the dissipation of turbine blade vibration energy and concepts are defined for the mechanical and pneumatic damping of blade vibration.
