Friction and fracture: richness and complexity in dynamic rupture

Understanding how things break and slide is of paramount importance to describe the dynamics of a broad range of physical systems. This includes day-to-day problems such as the breaking of a glass of wine or the sliding of skis on snow, but also engineerin ...

Propagation of planar three-dimensional buoyant hydraulic fractures

Andreas Möri

Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...

Uplift mechanics of unanchored liquid storage tanks subjected to lateral earthquake loading

Konstantinos Bakalis

Motivated by the seismic response of unanchored liquid storage tanks, their uplift mechanism under strong lateral loading is examined. Using three-dimensional finite element models, nonlinear static analysis is conducted to define the moment-rotation relat ...

ELSEVIER SCI LTD2021

The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equa ...

Stiffness, force and drift capacity of in-plane loaded modern unreinforced brick masonry walls

Bastian Valentin Wilding

In countries of low to moderate seismicity, such as Switzerland, unreinforced masonry (URM) is mainly used in residential buildings due to its good insulation capacity and fire resistance along with a fair compressive strength. URM walls however show a lim ...

Geomechanical modelling of CO₂ injection in deep aquifers

Chao Li

CO2 sequestration in deep geological formations is considered as a promising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected into a system that consists of a highly porous host reservoir c ...

A hydromechanical approach to assess CO2 injection-induced surface uplift and caprock deflection

Lyesse Laloui, Chao Li

This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of a mathematical model that incorporat ...

Fatigue behavior of hybrid GFRP-concrete bridge decks under sagging moment

Haifeng Fan, Yuqing Liu

This paper presents a new cost-effective hybrid GFRP-Concrete deck system that the GFRP panel serves as both tensile reinforcement and stay-in-place form. In order to understand the fatigue behavior of such hybrid deck, fatigue test on a full-scale specime ...

Sediment dynamics in the subaquatic channel of the Rhone delta (Lake Geneva, France/Switzerland)

Nicolas Le Dantec

With its smaller size, well-known boundary conditions, and the availability of detailed bathymetric data, Lake Geneva's subaquatic canyon in the Rhone Delta is an excellent analogue to understand sedimentary processes in deep-water submarine channels. A mu ...
