Numerical method for optimizing the design of a high-pressure apparatus with diamond anvils

A numerical method for optimizing the structure of a high-pressure unit with diamond anvils as pressure is created in the vessel is developed and realized in the form of a set of programs. The method includes the following: determination of the stress-strain state of the anvils and the deformable intervening layer of material; evaluation of the strength of the anvils; the development of a mathematical model to describe the dependence of the strength of the anvils on the parameters being optimized; determination of the optimum points of the model. A combination of optimum parameters is obtained, making it possible to reach a design pressure of 465 GPa. This pressure is 2.5 times higher than the pressure recorded in anvils with a similar pressure distribution.
