Abstract：Determining the best set of beveling parameters is an advantageous characteristic of the geometrical conditions for a cubic high-pressure tungsten carbide (WC) anvil, but it is almost impossible to deduce experimentally (much affected by defects in the material). In order to remove the affection of defects in materials, we investigate computational stress analyses in different beveling parameters of WC anvils by the finite element method. The results indicate that the rate of cell pressure transmitting and failure crack in the WC anvil monotonically increases with the bevel angle from 42° to 45°. Furthermore, there are two groups of actual users of beveled anvils, one group preferring 41.5°, which can decrease the rate of failure crack in WC anvil, the other group preferring 42°, which can increase the rate of cell pressure transmitting. This work would give an effective solution to solve the problem of the design of a cubic high-pressure WC anvil experimentally and will greatly help to improve the cubic high-pressure WC anvil type high pressure techniques.
