Microstructural enrichment functions based on stochastic Wang tilings
J. Novák, A. Kučerová, J. Zeman
This paper presents an approach to constructing microstructural enrichment functions to local fields in non-periodic heterogeneous materials with applications in Partition of Unity…
Analysis of a Fast Fourier Transform Based Method for Modeling of Heterogeneous Materials
J. Vondřejc, J. Zeman, I. Marek
The focus of this paper is on the analysis of the Conjugate Gradient method applied to a non-symmetric system of linear equations, arising from a Fast Fourier Transform-based homog…
A micromechanics-enhanced finite element formulation for modelling heterogeneous materials
J. Novák, Ł. Kaczmarczyk, P. Grassl +2
In the analysis of composite materials with heterogeneous microstructures, full resolution of the heterogeneities using classical numerical approaches can be computationally prohib…
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.…
Mori-Tanaka Based Estimates of Effective Thermal Conductivity of Various Engineering Materials
Jan Stránský, Jan Vorel, Jan Zeman +1
