The regularities, criteria, and mechanisms of crack branching are analyzed. Experimental work has been carried out to study the branching of cracks in brittle polymer and steel, and to measure the crack velocity by breaking conductive strips. A hypothesis of the physical mechanism of crack branching is proposed.
