On the dynamic fracture of structural metals,n of experimental results to elastic-plastic analyses, and attempts to clarify the role of material inertia and plasticity in the dynamic crack growth process. In addition the relation of crack growth criteria to micromechanical void growth models is considered..Potential problems in the analysis of

,Mechanics of crack curving and branching — a dynamic fracture analysis, correlated best with available experimental data. The crack branching criterion requires as a necessary condition, a critical dynamic stress intensity factor, .., and a sufficient condition involving the crack curving criterion. The criteria are used to predict crack curving and crack branching in

Dynamic fields generated by rapid crack growth,analytical results for near-tip dynamic fields as predicted by linear elastic fracture mechanics. Next, exact expressions are derived for dynamic crack-line strains, for mode-III crack propagation in a nonlinear elastic material and in an elastic perfectly-plastic material. These expressions are val

Numerical studies in dynamic fracture mechanics,mesh” finite-element procedures are examined. Simple procedures, using a moving mesh of conventional isoparametric elements in conjunction with certain path-independent integrals for the evaluation of stress-intensity factors for a dynamically propagating crack are presented.

Application of dynamic shear crack models to the study of the earthquake faulting process, finite cracks, several numerical approaches to this problem have been taken, of which the numerical boundary integral method is here described in detail. The process of crack growth can be determined by the use of a fracture criterion. Since the material properties such as fracture strength and fri

,On the measurement of dynamic fracture toughnesses — a review of recent work,n that these dynamic effects can be significant: For cracks at arrest the stress condition is still dynamic and not static although the crack velocity has become zero. Dynamic effects become small only for small crack velocities or small crack jumps or for specially designed specimens. It is shown t

Applications of dynamic fracture mechanics for the prediction of crack arrest in engineering structfor analyses that focus on the entire crack initiation/propagation/arrest process — as opposed to static analyses which consider only the end points — as dynamic effects are not always significant in a crack run/arrest event. The importance of integrating experimental and computational work in this
