“…In practice, significantly larger scale differences are expected; consider e.g. the example of local failure in large-scale models, as in the study of Ha-Minh et al (2011). In such cases, the relative number of reppoints and sampling points will be significantly smaller, which means that the computational gain will be significantly larger than that reported here.…”

“…Another advantage is that a number of QC frameworks (Knap and Ortiz, 2001;Eidel and Stukowski, 2009;Beex et al, 2011Beex et al, , 2012a do not require a handshaking region or coupling procedure between fully resolved domains (in which the exact lattice model is recovered) and coarse domains (in which an approximation is made). Several other multiscale approaches require such a coupling procedure (Shenoy et al, 1999;Xiao and Belytschko, 2004;Fish et al, 2007;Ha-Minh et al, 2011).…”

Lattice models and discrete networks naturally describe mechanical phenomena at the mesoscale of fibrous materials. A disadvantage of lattice models is their computational cost. The quasicontinuum (QC) method is a suitable multiscale approach that reduces the computational cost of lattice models and allows the incorporation of local lattice defects in large-scale problems. So far, all QC methods are formulated for conservative (mostly atomistic) lattice models. Lattice models of fibrous materials however, often require non-conservative interactions. In this article, a QC formulation is derived based on the virtual-power of a non-conservative lattice model. By using the virtual-power statement instead of force-equilibrium, errors in the governing equations of the force-based QC formulations are avoided. Nevertheless, the non-conservative interaction forces can still be directly inserted in the virtualpower QC framework. The summation rules for energy-based QC methods can still be used in the proposed framework as shown by two multiscale examples.

The goal of this study is to initiate a "test-calculation dialogue" on low velocity/low energy impact tests in laminated composites. The different types of impact damage developing during an impact test, i.e. matrix cracking, fiber failure, interface delamination and permanent indentation, are simulated. The bibliography shows a general lack of detailed validation of impact modeling and the originality of this work is to use refined and complementary experimental data to build and validate a numerical model. The good correlation between the model and this refined experimental database gave us relative confidence in the model, despite a few nonstandard material parameters.Permanent indentation was particularly focused and studied. Then we propose an original scenario to create permanent indentation, with a debris blocking phenomenon in the matrix cracks, as well as the corresponding model. The fiber failure model was set up using an original formulation between the integration points of the volume element in order to dissipate a constant energy release rate per unit area. Finally the model was used to evaluate the distribution of the dissipated energy among the different damage types, and demonstrated an interesting distribution between fiber failure and delamination.

“…Local events such as element failure can no longer be incorporated in these approaches, but they can still easily deal with large rotations (Sharma and Sutcliffe, 2004) and locking (Sharma and Sutcliffe, 2004;Hamila and Boisse, 2008). Also a number of multiscale approaches can be used to increase the efficiency of large-scale computations (Nilakantan et al, 2010;Ha-Minh et al, 2011;Beex et al, 2011).…”

Lattice models employing trusses and beams are suitable to investigate the mechanical behavior of woven fabrics. The discrete features of the mesostructures of woven fabrics are naturally incorporated by the discrete elements of lattice models. In this paper, a lattice model for woven materials is adopted which consists of a network of trusses in warp and weft direction, which represent the response of the yarns. Additional diagonal trusses are included that provide a resistance against relative rotation of the yarns. The parameters of these families of discrete elements can be separately identified from tensile experiments in three in-plane directions which correspond with the orientations of the discrete elements. The lattice model and the identification approach are applied to electronic textile. This is a fabric in which conductive wires are incorporated to allow the embedment of electronic components such as light-emitting diodes. The model parameters are established based on tensile tests on samples of the electronic textile. A comparison between the experimental results of an out-of-plane punch test and the simulation results shows that the lattice model and its characterization procedure are accurate until extensive biaxial tensile deformation occurs.
