✦ Synopsis

Large-scale discrete element simulations, combined ÿnite-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 ÿnite-discrete element method is reported. The algorithm is based on accurate approximation of experimental stress-strain curves for concrete in tension.

In this approach, the discontinuity region is divided into two regions. One is a finite region with arbitrary inhomog
