Study of Influence of Superimposed Hydrostatic Pressure on Ductility in Ring Compression Test
Abstract
The effects of superimposed hydrostatic pressure on the ductility of compressed rings are investigated numerically by using the finite element method and employing the Johnson–Cook (J–C) model. The ductility and fracture strain increase considerably by imposing hydrostatic pressure, which delays the initiation of cracks at the corners of the rings. Furthermore, the sensitivity of the ductile fracture parameters in the J–C model on …
