A scalable 3D fracture and fragmentation algorithm based on a hybrid, discontinuous Galerkin, Cohesive Element method
Computer Methods in Applied Mechanics and Engineering, 2020Co-Authors: Raul Radovitzky, A. Seagraves, M. Tupek, L. NoelsAbstract:A scalable algorithm for modeling dynamic fracture and fragmentation of solids in three dimensions is presented. The method is based on a combination of a discon- tinuous Galerkin (DG) formulation of the continuum problem and Cohesive Zone Models (CZM) of fracture. Prior to fracture, the flux and stabilization terms aris- ing from the DG formulation at interElement boundaries are enforced via interface Elements, much like in the conventional intrinsic Cohesive Element approach, albeit in a way that guarantees consistency and stability. Upon the onset of fracture, the traction-separation law (TSL) governing the fracture process becomes operative without the need to insert a new Cohesive Element. Upon crack closure, the rein- statement of the DG terms guarantee the proper description of compressive waves across closed crack surfaces. The main advantage of the method is that it avoids the need to propagate topo- logical changes in the mesh as cracks and fragments develop, which enables the indistinctive treatment of crack propagation across processor boundaries and, thus, the scalability in parallel computations. Another advantage of the method is that it preserves consistency and stability in the uncracked interfaces, thus avoiding issues with wave propagation typical of intrinsic Cohesive Element approaches. A simple problem of wave propagation in a bar leading to spall at its center is used to show that the method does not affect wave characteristics and as a consequence properly captures the spall process. We also demonstrate the ability of the method to capture intricate patterns of radial and conical cracks arising in the impact of ceramic plates which propagate in the mesh impassive to the presence of processor boundaries.Peer reviewe

Advances in Cohesive Zone Modeling of Dynamic Fracture
Dynamic Failure of Materials and Structures, 2009Co-Authors: A. Seagraves, Raul RadovitzkyAbstract:In this chapter, we review the state of the-art in computational methods for modeling dynamic fracture of brittle solids based on the popular Cohesive Element approach. The discussion includes a detailed review of the underlying theory, its implementation via interface Elements in its two different flavors: the intrinsic and extrinsic approach, as well as the application of the method to different concrete problems in dynamic fracture. Limitations and numerical issues are discussed in detail. As a means to address some of these issues, we describe an alternative approach based on a discontinuous Galerkin (DG) reformulation of the continuum problem that exploits the virtues of the existing Cohesive Element methods. The scalability and accuracy of the DG method for fracture mechanics is demonstrated through wave propagation and spall tests in ceramics. Lastly, some unresolved open problems and numerical issues pertaining to Cohesive zone modeling of fracture are briefly discussed.

a Cohesive Element model for mixed mode loading with frictional contact capability
International Journal for Numerical Methods in Engineering, 2013Co-Authors: Leonardo Snozzi, Jean-françois MolinariAbstract:We present a model that combines interface debonding and frictional contact. The onset of fracture is explicitly modeled using the well-known Cohesive approach. Whereas the debonding process is controlled by a new extrinsic traction separation law, which accounts for mode mixity, and yields two separate values for energy dissipation in mode I and mode II loading, the impenetrability condition is enforced with a contact algorithm. We resort to the classical law of unilateral contact and Coulomb friction. The contact algorithm is coupled together to the Cohesive approach in order to have a continuous transition from crack nucleation to the pure frictional state after complete decohesion. We validate our model by simulating a shear test on a masonry wallette and by reproducing an experimental test on a masonry wall loaded in compression and shear.

How the obscuration-zone hypothesis affects fragmentation: Illustration with the Cohesive-Element method
International Journal of Fracture, 2011Co-Authors: Marion Estelle Chambart, Sarah Levy, Jean-françois MolinariAbstract:The problem of fragmentation prediction is at the origin of various analytical models. Among them, we focus on the ones introducing the idea of obscured zones. They assume that when a crack initiates at a defect, a stress release wave propagates away from the crack and protects the region encompassed by the wave from any further crack initiation. In this paper, we show by the use of numerical simulations that this assumption is only valid at high strain rates. The limit of its accuracy is even pushed to higher strain rates when the fragmentation process becomes more complex, that is to say when crack propagation, bifurcation or coalescence together with wave reflections are implied. In these cases, fragmentation lasts longer than the time needed to completely obscure the whole specimen and the obscured zone theory for fragmentation appears inadequate. We use the Cohesive-Element method to describe the damage and failure of the material considered.

the Cohesive Element approach to dynamic fragmentation the question of energy convergence
International Journal for Numerical Methods in Engineering, 2007Co-Authors: Jean-françois Molinari, Ramesh Raghupathy, George A. Gazonas, A Rusinek, Fenghua ZhouAbstract:The Cohesive Element approach is getting increasingly popular for simulations in which a large amount of cracking occurs. Naturally, a robust representation of fragmentation mechanics is contingent to an accurate description of dissipative mechanisms in form of cracking and branching. A number of Cohesive law models have been proposed over the years and these can be divided into two categories: Cohesive laws that are initially rigid and Cohesive laws that have an initial elastic slope. This paper focuses on the initially rigid Cohesive law, which is shown to successfully capture crack branching mechanisms in simulations. The paper addresses the issue of energy convergence of the finite-Element solution for high-loading rate fragmentation problems, within the context of small strain linear elasticity. These results are obtained in an idealized one-dimensional setting, and they provide new insight for determining proper Cohesive zone spacing as function of loading rate. The findings provide a useful roadmap for choosing mesh sizes and mesh size distributions in two and three-dimensional fragmentation problems. Remarkably, introducing a slight degree of mesh randomness is shown to improve by up to two orders of magnitude the convergence of the fragmentation problem.

Numerical convergence of the Cohesive Element approach in dynamic fragmentation simulations
