摘要：

The three-dimensional shape and velocity of propagating cracks in the hydrostatic stress condition were studied by using gelatin, the physical properties of which were controlled to be constant. Various liquids were injected in gelatin to form liquid-filled cracks. The directions of the crack growth and the propagation of an isolated crack are governed by the density difference between injected liquid and gelatine (Δρ), that is, a buoyancy. The propagation of a crack has two critical values: 1) the transition value to brittle fracture; and 2) the value where segmentation begins to occur. The condition of a stable isolated crack formation is discussed. -from Author
