Time-Dependent Deformation of Sandstone due to Chemical Corrosion: An Investigation Using the Heterogeneous Grain-Based Phase-Field Method

Alexandra Roma Larisa Kushnir

Fractures are diverse geological features. Despite extensive research on their varied geometries and growth mechanisms, there has been relatively little focus on how acid-rock interactions, such as reactive transport and precipitation, influence crack grow ...

Fluid Chemistry Effect on Localized and Ductile Deformation of a Porous Sandstone

Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer, Francesco Lazari

In geological reservoirs, pore fluid chemistry can affect rock strength by inducing mineral dissolution, precipitation, and alteration, among other processes. Increasing pressure and temperature can shift deformation from localized to ductile, decreasing p ...

Influence of the Horizontal-to-Vertical Compressive Strength of Hollow Clay Bricks on the In-Plane Drift Capacity of Unreinforced Masonry Walls

Katrin Beyer, Savvas Saloustros, Ernesto Andrés Inzunza Araya

The seismic damage of masonry walls is reflected in cracks that tend to start at the head and bed joints and subsequently propagates through the masonry units. In this regard, the horizontal-to-vertical compressive strength ratio of bricks might have the a ...

Refractive Index Matched (RIM) PIV in Free Surface Flows of Particle-Laden Yield Stress Fluids

Christophe Ancey, Yanan Chen

Flow of lava, avalanches, mudslides, and many geophysical and planetary flow systems are examples of free-surface flows of Yield Stress Fluids (YSFs). This category of fluids is known for its dual behavior below- and above a yielding threshold for the appl ...

Shear and steel-fibre reinforcement for the punching resistance of flat slabs at internal and edge columns

Diego Hernández Fraile

Reinforced concrete flat slabs consist of a continuous, thin concrete plate that rests on a grid of columns. The supporting surface of the columns is very small compared to the floor plan dimensions, leading to concentrations of shear forces near the colum ...
