Quasicontinuum Approach Applied to Inelastic Materials
K. Mikeš
pages 200 - 201, full text

The quasicontinuum (QC) method was proposed by Tadmor, Ortiz and Phillips [3] in 1996. The original application of this computational technique was a simulation of large atomistic systems with regular lattices described by long-range conservative interaction potentials. Extension to nonconservative interaction was done by Beex et al. [1]. In the present work, the QC technique is applied to an irregular set of particles connected by discrete plastic links representing e.g. a fibrous material. QC models for plastic materials are constructed within the framework of the microplane theory. Accuracy, efficiency and specific properties of QC microplane models are evaluated by comparison of results with the pure particle approach.
