Modeling size effects associated with tensile fracture initiation from a wellbore

Brice Tanguy Alphonse Lecampion

This paper investigates different tensile fracture initiation criteria on the plane-strain configuration of a defect-free openhole wellbore. It aims to model the effect of the internal pressurization of a wellbore drilled in the direction of one of the pri ...

Poinçonnement non symétrique des dalles en béton armé

Luca Tassinari

Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...

Post-punching behavior of reinforced concrete slabs

Yaser Mirzaei

Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, ...

Failure in multiphase geomaterias

Lyesse Laloui

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

When structural elements are subjected to compressive loads, the shear forces and stresses induced by second- order effects may lead to shear failure prior to compressive failure. This is particularly likely to occur in the case of pultruded glass fiber-re ...

Ductile-to-brittle transition in tensile failure of particle reinforced metals

Andreas Mortensen, Andreas Rossoll, Aude Hauert

We present an analytical micromechanical model designed to simulate the tensile stress-strain behaviour and failure of damaging composites containing a high volume fraction of reinforcing particles. One internal damage micromechanism is considered, namely ...

Through-thickness performance of adhesive connections between FRP bridge decks and steel main girders

Martin Schollmayer

FRP bridge decks offer several advantages compared with conventional concrete bridge decks, particularly their much lower weight, but also their resistance against corrosion as well as easier installation and maintenance. The poorly conceived methods avail ...

Desiccation cracking of soils

Lyesse Laloui, Hervé Péron

The scope of this paper is to present the global mechanisms of soil desiccation, including drying shrinkage and cracking. The paper first reviews the basic processes that are beneath the word “desiccation”. Then the results of an experimental study of desi ...

Progressive failure process of adhesively bonded joints composed of pultruded GFRP

Thomas Keller, Ye Zhang

Adhesively bonded joints are being used increasingly in civil engineering structures, especially for joints comprising pultruded glass fiber reinforced polymer (GFRP) laminates. The layered material architecture, however, leads to a complex delamination fa ...

The constant improvement of polymer composite materials has allowed their integration in many industrial fields where their mechanical and chemical properties are apparently attractive. Mixed metal-composite insulators are now increasingly used for high vo ...
