Large‑scale discrete element and combined finite‑discrete element simulations involve many interacting bodies that deform and fracture, highlighting the need for a robust fracture algorithm capable of handling simultaneous multiple fracturing. The study reports a fracture model for initiation and propagation of mode I cracks in concrete within the combined finite‑discrete element method. The algorithm approximates experimental stress–strain curves for concrete in tension to accurately model crack initiation and propagation. © 1999 John Wiley & Sons, Ltd.
Large-scale discrete element simulations, combined finite-discrete element simulations as well as a whole range of related problems, involve a large number of separate bodies that interact with each other and in general deform and fracture. In this context there is a need for a robust fracture algorithm applicable to simultaneous multiple fracturing of large numbers of bodies. In this work a fracture model for both initiation and propagation of mode I loaded cracks in concrete in the context of the combined finite-discrete element method is reported. The algorithm is based on accurate approximation of experimental stress–strain curves for concrete in tension. Copyright © 1999 John Wiley & Sons, Ltd.
