✦ Synopsis

Glass tubes were fractured by internal pressure under atmospheric or superimposed hydrostatic pressure. It is found that the crack length at bifurcation is significantly increased by superimposed hydrostatic pressures. The dynamic energy release rate for a crack propagating with superimposed hydrostatic pressure is calculated. It is shown that the pressure effect on crack length at bifurcation may be explained by combining the energy balance condition and the Yoffe's concept for crack bifurcation.
