The Value of Dynamic Fracture Toughness and Its Dependence on Material Properties and Loading Conditions

Abstract

Investigation of dynamic fracture of long brittle beams under different loading conditions was effected under ARO Grant DAAG29-78-G-0086. The work has proceeded in two distinct areas - the numerical solution of crack propagation problems using a finite difference code and the analytical solution of some beam fracture problems using several one-dimensional theory formulations.
