  • Based on the principle of massive support, the parameters of ultra-high pressure tungsten carbide (WC) anvil have been stuied by finite element method.The results indicate that the technologies of radius beveling and concave region can enhance the performence of ultra-high pressure WC anvil, by decreasing the focus phenomenon of stress and increasing the lateral support, respectively.Further more, the pressure transmission efficiency of new anvil is higher compared with the traditional anvil, which can be enhanced about 58.5%.The rate of cracking in new anvil decreases about 33% than that of traditional anvil.The highest sample cell pressure generation by new anvil increases about 44.2% compared with the traditional anvil, which changes from 6.63 GPa to 9.56 GPa.This work represents a new structure of ultra-high pressure WC anvil for study on the novel structure and properties of matter, design and synthesis of functional materials.
