摘要: The shape of a tapered crack is more alike cracks in brittle materials than an elliptical crack. deformation and stress fields for are therefore estimated hydrostatic pressure tensional by applying the method complex potentials. quite similar, which suggests that can be used as model general. However, has larger at tip, show fracture propagation occur lower applied stresses A fluid filled fractures account their discontinuous propagation. observed large scale volcanic eruptions where generates seismic activity.
