  • Based on finite element method, the model of tungsten carbide (WC) anvil and the criterion for crack of WC anvil used in China-type cubic high pressure apparatus have been founded successfully. The simulation results indicated that the criterion for crack of WC anvil should make the reference point at the end of bevel edge. According to the von Mises criterion, we know that in the area of anvil surface and bevel edge, the cracks are often arising around the bevel edge. In the axis of anvil, the cracks are often arising at the place which is 30 mm below anvil surface. This study may greatly help to design new type WC anvil and improve the large volume cubic anvil type high pressure techniques.
