“…Moreover mixed-mode experimental results as reported by Sutton et al (2000) have been reproduced by our model with good agreement. To conclude the series of numerical simulations, a force-free crack propagation is also shown as an application of the model.…”

“…In fact, one knows that in brittle fracture the two paths are clearly distinct (cf., e.g., Allaire et al 2011). However, for ductile fracture this is no more the case as laboratory experiments and numerical simulations show (Maccagno and Knott 1992;Amstutz et al 1995;James and Swenson 1999;Sutton et al 2000) (Fig. 12).…”

“…A first series of ductile crack propagation results with such a temperaturedependence have been performed and discussed in Van Goethem et al (2011) from which the present contribution has followed. However as opposed to the present model the crack propagation direction was calculated with an empirical law based on a CTOD 1 criterion which is known to provide excellent qualitative results for both brittle and ductile fracture (cf., e.g., Sutton et al 2000;Areias et al 2009Areias et al , 2011b.…”

In this paper we assess a crack propagation criterion based on the notion of configurational force in the spirit of Gurtin (Configurational forces as basic concepts of continuum physics. Applied mathematical sciences. Springer, Berlin, 2000). We extend the theory of Gurtin to finite strain elasto-plastic fracture and in addition take thermal effects into account. The global model is a system of nonlinear and non-smooth equations which are solved directly with a finite element discretization. Comparison with laboratory experiments is provided, thereby showing that the concept of configurational force can be successfully used for computational damage-based fracture tests on ductile materials.

“…An alternative is the virtual crack closure technique by Ribicki [57] and further developed by Krueger [40]. Furthermore, since it is based on the crack tip opening displacement (CTOD) and it is known to have high predictive capabilities for large strain plasticity [43,60]. A short summary of the application by Krueger is provided here.…”

Rotation axes are the crack front edges (respectively nodes in surface discretizations) and each rotated edge affects the position of only one or two nodes. Modified positions of the entities minimize the difference between the predicted crack path (which depends on the specific propagation theory in use) and the edge or face orientation. The construction of all many-to-many relations between geometrical entities in a finite element code motivates operations on existing entities retaining most of the relations, in contrast with remeshing (even tip remeshing) and enrichment which alter the structure of the relations and introduce additional entities to the relation graph (in the case of XFEM, enriched elements which can be significantly different than classical FEM elements and still pose challenges for ductile fracture or large amplitude sliding). In this sense, the proposed solution has algorithmic and generality advantages. The propagation algorithm is simpler than the aforementioned alternatives and the approach is independent of the underlying element used for discretization. For history-dependent materials, there are still some transfer of relevant quantities between meshes. However, diffusion of results is more limited than with tip or full remeshing. To illustrate the advantages of our approach, two prototype models are used: tip energy dissipation (LEFM) and cohesive-zone approaches. The Sutton crack path criterion is employed. Traditional fracture benchmarks and newly proposed verification tests are solved. These were found to be very good in terms of crack path and load/deflection accuracy. Nomenclature
