It is generally accepted that the flow stress as well as the strain-to-fracture of brittle materials is increased by superposed hydrostatic pressure. However, the fundamentals underlying the effect of hydrostatic pressure on brittle materials are yet to be explained. Torsion tests were carried out on cast iron under hydrostatic pressure up to 4000 kg/cm^2 in order to elucidate the effect of hydrostatic pressure on the deformation and fracture of brittle materials. It is shown in this paper that the deformation and fracture properties of cast iron are strongly influenced by the currently acting hydrostatic pressure rather than the strain history of the material. Anisotropy of cast iron usually observed in torsion tests is decreased by hydrostatic pressure.
