Dynamic fracture growth and interaction in one dimension

Abstract The present study considers concepts relating fracture energy and fracture dynamics. Analyses of Mott are expanded to explicitly account for energy dissipation during the fracture process. Expressions are obtained for the nominal fragment size, fracture time, and dynamic fracture strain. It is shown that communication between growing fractures is relatively slow. Numerical analysis is used to examine the interaction of ductile fractures and the conditions that may lead to arrest or completion of growing fractures.
