Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.About:

Wear of rocks by water flow
TL;DR: In this paper, the authors summarise recent results obtained from wear and erosion tests performed on rocks and cementitious composites, and define relevant wear types, failure modes, threshold conditions, parameter influence, and resistance parameters.

Three-dimensional FDEM numerical simulation of failure processes observed in Opalinus Clay laboratory samples
TL;DR: In this paper, a 3D hybrid finite-discrete element method (FDEM) was used to investigate the development of an excavation damaged zone (EDZ) around tunnels in a clay shale formation known as Opalinus Clay.
Journal ArticleDOI
Simulation of fracture of cementitious composites with explicit modeling of microstructural features
TL;DR: In this paper, the authors analyzed the fracture of planar microcracks in cementitious composites using the cohesive surface methodology, where the presence of aggregates in the cement matrix was explicitly accounted for.

Size effect tests of normal-strength and high-strength RC columns subjected to axial compressive loading
TL;DR: In this paper, a series of axial compressive tests of 43 reinforced concrete (RC) columns with different sizes (in the ratio 1:2:3:4), different concrete strength grades (i.e. 1.5% and 2.5%) and transversal ratios of 0, 0.65%, 0.94% and 1.2-1.5) were conducted.

Interlaminar shear behavior of continuous and short carbon fiber reinforced polymer composites fabricated by additive manufacturing
TL;DR: In this article, the authors investigated the interlaminar shear behavior of 3D printed CFRP composites fabricated by fused deposition modeling (FDM) through a combined experimental and numerical study.
