Abstract

The aim of the work is to determine the influence of the bevel size of the double-beveled anvils on the level of generated pressure in the six-anvil cubic apparatus and the anvil strength. Computer modeling using the finite element method of compression of a pyrophyllite container between anvils with a different bevel size has been carried out, and the limit states of the anvils have been investigated. It is shown that the bevel size has practically no effect on the pressure distribution generated in the container. Reducing the value of the bevel size leads to an increase in the magnitude of equivalent stresses in the region on the edges of the flat section of the working surface. At small lengths, the destruction of the anvil ribs is possible due to their insufficient lateral support.
