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…
A reduced order model for geometrically parameterized two-scale simulations of elasto-plastic microstructures under large deformations
Theron Guo, Ondřej Rokoš, Karen Veroy
In recent years, there has been a growing interest in understanding complex microstructures and their effect on macroscopic properties. In general, it is difficult to derive an eff…
A Comparative Study of Enriched Computational Homogenization Schemes Applied to Two-Dimensional Pattern-Transforming Elastomeric Mechanical Metamaterials
S. O. Sperling, T. Guo, R. H. J. Peerlings +3
Elastomeric mechanical metamaterials exhibit unconventional behaviour, emerging from their microstructures often deforming in a highly nonlinear and unstable manner. Such microstru…
Bayesian Approach to Micromechanical Parameter Identification Using Integrated Digital Image Correlation
Liya Gaynutdinova, Ondřej Rokoš, Jan Havelka +2
Materials with heterogeneous structures exhibit complex physical processes such as delamination, cracks, and plasticity, which require micromechanical parameters for understanding.…
Integrated Digital Image Correlation for Micro-Mechanical Parameter Identification in Multiscale Experiments
O. Rokoš, R. H. J. Peerlings, J. P. M. Hoefnagels +1
Micromechanical constitutive parameters are important for many engineering materials, typically in microelectronic applications and material design. Their accurate identification p…
