Abstract The main goal of this review is to provide a thorough scientific understanding of the interplay between stochastics and mechanics, by classifying what can be achieved by representing mechanical system parameters in terms of deterministic val

Multi-surface plasticity model for concrete with 3D hardening/softening failure modes for tension, compression and shear

Computers and Structures, Elsevier, 2019, 221, pp.74-90. ⟨10.1016/j.compstruc.2019.05.009⟩

In this work we develop multi-surface plasticity model which can reproduce the inelastic behavior and failure modes of concrete in tension, compression and shear. The main novelty of the proposed concrete model can also capture all different phases o

Reduced model of macro-scale stochastic plasticity identification by Bayesian inference: Application to quasi-brittle failure of concrete

Autor: Adnan Ibrahimbegovic, Emir Karavelić, Hermann G. Matthies

Publikováno v: Computer Methods in Applied Mechanics and Engineering
Computer Methods in Applied Mechanics and Engineering, Elsevier, 2020, 372, pp.113428-. ⟨10.1016/j.cma.2020.113428⟩

In this paper we deal with a probability-based scale bridging for concrete material when passing the detailed information at the meso-scale (the scale where the aggregate vs. cement microstructure is visible) with a Voronoi-cell based microstructure

Computer Methods in Applied Mechanics and Engineering, Elsevier, 2019, 344, pp.1051-1072. ⟨10.1016/j.cma.2017.09.013⟩

International audience; Prediction of failure mechanisms in concrete is a fairly complex task due to heterogeneous concrete microstructure, localization process triggered by cracks, multiple crack interactions during their growth and coalescence, and
