Abstract
Mixed-mode dynamic crack propagation in concrete is studied using the eleme nt-free Galerkin (EFG) method. The EFG methodology allows for arbitrary cra ck growth in terms of direction and speed. A fracture process zone (FPZ) mo del is used for fracture in concrete. Comparisons are made to mode I and mi xed-mode experiments on concrete three-point-bend specimens. Good agreement is achieved with the experimental results. (C) 2000 Elsevier Science S.A. All rights reserved.
