Abstract.
While the energy is released rapidly from a local area of the materials where the stress is concentrated, the transient elastic waves will be generated.

Comparison of irradiation creep of nitride fuel and properties of cladding materials shows that under parameters of fast reactors and typical design of fuel element it is impossible to implement restraining of external nitride swelling.
Irradiation creep is a key parameter for determining the features of the fuel cladding mechanical interaction with swelled fuel.
This makes it possible with a lack of data to estimate the creep of nitride fuel under irradiation, using existing theoretical predictions about the effect of irradiation on self-diffusion in materials.

Experiment
Materials: HDPE,DMDA-8008,the Dushanai Subsidiary Company, China Petrifies.
The raw materials including HDPE, wood flour, MAH and initiator (DCP or BPO) were mixed together for 5 min in the SHR high-speed blender.
The reason for this may be that BPO has almost decomposed in the period from materials entering stuff canister to resin melting due to its high activity.

Abstract.
Actually, with the statistical probability method these parameters as illustrated in Fig.1 can be calculated based on the maximum grain indentation depth, which developed iteratively through the materials removal rates.
The materials removal rates can be obtained both analytically and experimentally.
