Abstract:
With the explicit dynamic finite element method, the rolling process of U10Mo/Al dispersion-type fuel plate was simulated, and the effect of rolling processing parameter on the rolling behavior and contact pressure of fuel plate was investigated. Finite element simulation results show that the rolling speed is with obvious effect on the strain rate of fuel meat. The deformation and stress condition of fuel meat would be increased with the increasing of the reduction rate. As the friction factor increasing, the spread rate reduces gradually, but the stress on fuel meat grows accordingly.
