Abstract

During the diamond dust synthesis the most stressed parts of a high-pressure apparatus are dies. They are subjects to all-around nonuniform compression. The criterion for strength estimation of such elements is required with the next conditions: the high-alloy material properties should be considered, the geometrical interpretation of the criterion should be a continuous function in the all range of definition. In this article the criterion that suits the necessary conditions was proposed. It is a linear function of the stress tensor component. Thus it can be used for the estimation of safety factor on yielding and destruction. The efficiency of the proposed criterion using for the strength calculation of a high-pressure apparatus dies was proved by comparison with the known strength criteria.
