Variational Quasicontinuum methods for lattice structures with plasticity and localized damage
Original language description
Lattice networks with dissipative interactions are successfully employed as discrete micro- or meso-scale models for fibrous materials and heterogeneous solids. Their suitability stems from rather straightforward incorporation of nonlocalities, large deformations, and complex constitutive laws of individual links. Various applications can be found in textiles, paper, polymers, or concrete. Because the application scale is usually significantly larger than that of individual interactions, full lattice simulations are computationally prohibitive. The original (conservative) version of the QuasiContinuum (QC) method has been developed to overcome such a limitation in atomistic systems. This approach requires, however, certain extensions before it becomes applicable also to dissipative systems. For instance, internal variables must be introduced and inhomogeneities due to propagating dissipative phenomena, such as fracture and damage, addressed. This presentation ergo focuses on several aspects of the QC method related to materials that can be modelled as regular homogeneous dissipative lattice networks.
