Force–displacement response of in-plane loaded unreinforced brick masonry walls: the Critical Diagonal Crack model

This article introduces an analytical model to compute the monotonic force–displacement response of in-plane loaded unreinforced brick masonry walls accounting for walls failing in shear or ﬂexure. The masonry wall is modelled as elastic in compression wit ...

Effect of fluid viscosity on fault frictional behavior

Marie Estelle Solange Violay, Chiara Cornelio

Tectonic faults are often lubricated by viscous fluids which can have different natures e.g. gas, water, brine, melt and viscosities varying over 7 order of magnitude (from 10-4 for water to 103 Pa s-1 for a melt at high temperature). Moreover, understandi ...

Scaling laws for the mechanics of loose and cohesive granular materials based on Baxter's sticky hard spheres

Johan Alexandre Philippe Gaume, Henning Löwe

We have conducted discrete element simulations (PFC3D) of very loose, cohesive, granular assemblies with initial configurations which are drawn from Baxter's sticky hard sphere (SHS) ensemble. The SHS model is employed as a promising auxiliary means to ind ...

Effect of End-Restraint Conditions on Energy Pile Behavior

Lyesse Laloui, Melis Sütman

Energy piles are deep foundation elements designed to utilize the relatively constant temperature of the ground for efficient heating and cooling of the buildings while at the same time serve as foundations. The temperature changes during the operation of ...

From rock to magma and back again: The evolution of temperature and deformation mechanism in conduit margin zones

Marie Estelle Solange Violay, Michael Heap

Explosive silicic volcanism is driven by gas overpressure in systems that are inefficient at outgassing. The zone at the margin of a volcanic conduit-thought to play an important role in the outgassing of magma and therefore pore pressure changes and explo ...

Modelling of fluid injection into a frictional weakening dilatant fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Fluid injection at a pressure below the local minimum principal total stress in a fault may (re)activate shear crack propagation (hydroshearing). Because of the presence of asperities along the fault's surfaces, the fault hydraulic width increase with the ...

Computational comparison of aortic root stresses in presence of stentless and stented aortic valve bio-prostheses

Alfio Quarteroni, Christian Vergara, Elena Faggiano

We provide a computational comparison of the performance of stentless and stented aortic prostheses, in terms of aortic root displacements and internal stresses. To this aim, we consider three real patients; for each of them, we draw the two prostheses con ...

Avalanches in dry and saturated disordered media at fracture in shear and mixed mode scenarios

Jean-François Molinari, Enrico Milanese, Okan Yilmaz

We investigate shear and mixed mode fracture scenarios in inhomogeneous dry and fully saturated porous media with a 2D central force lattice model. For the fully saturated case we adopt the extended Biot's theory. The bars of the lattice break only under t ...
