摘要：
A novel device with a large cavity is investigated with regard to pressure capacity. This device is the multilayer stagger-split die (MSSD) that employs one or more supported rings and the multilayered divided body assemblage. The divided bodies are arranged in a staggered manner between adjacent layers. The pressure capacity of this device is calculated based on different failure criteria and using the simulation-based optimization approach. The results are compared with those of the belt-type die (BTD). A comparative experiment is also carried out to verify the simulated results. We conclude that the conditionality of pressure capacity of MSSD is related to die size. And MSSD can bear higher pressure than the BTD.
