Numerical simulation of multilayer stagger-split die and experiment on the bearing capacity

Abstract

A high pressure device, multilayer stagger-split die, is investigated by finite-element analysis. We simulated the process of compressing pyrophyllite according to the Drucker–Prager criterion. Simulated results of both dies in the axial and radial directions are displayed and compared using the contour and path plots. We obtained the rate of pressure decay in the radial and axial directions, and analyzed the pressure distribution of the pressed pyrophyllite. The results demonstrate that in almost the same condition, the pressure of the multilayer stagger-split die is about 13.6% higher than that of the belt die, and the experimental result is higher.
