Investigations into the Phenomenon of Crack Branching
A particularly peculiar phenomenon in fracture mechanics is bifurcation or crack branching, which occurs when a crack runs rapidly under high stress intensity. Bifurcation also occurs with a crack under simple tensile stress, which initially propagates perpendicularly to the tensile stress that has been applied to the crack. Various criteria have been proposed for specifying branching conditions in brittle materials.
