Extended Quasicontinuum Methodology for Highly Heterogeneous Discrete Systems
Benjamin Werner, Ondřej Rokoš, Jan Zeman
Lattice networks are indispensable to study heterogeneous materials such as concrete or rock as well as textiles and woven fabrics. Due to the discrete character of lattices, they…
eXtended Variational Quasicontinuum Methodology for Lattice Networks with Damage and Crack Propagation
Ondřej Rokoš, Ron H. J. Peerlings, Jan Zeman
Lattice networks with dissipative interactions are often employed to analyze materials with discrete micro- or meso-structures, or for a description of heterogeneous materials whic…
An adaptive variational Quasicontinuum methodology for lattice networks with localized damage
Ondřej Rokoš, Ron H. J. Peerlings, Jan Zeman +1
Lattice networks with dissipative interactions can be used to describe the mechanics of discrete meso-structures of materials such as 3D-printed structures and foams. This contribu…
Localization Analysis of an Energy-Based Fourth-Order Gradient Plasticity Model
Ondřej Rokoš, Jan Zeman, Milan Jirásek
The purpose of this paper is to provide analytical and numerical solutions of the formation and evolution of the localized plastic zone in a uniaxially loaded bar with variable cro…
Localization analysis of variationally based gradient plasticity model
Milan Jirásek, Ondřej Rokoš, Jan Zeman
The paper presents analytical or semi-analytical solutions for the formation and evolution of localized plastic zone in a uniaxially loaded bar with variable cross-sectional area.…
