Numerical simulation of instability of thin reinforced concrete walls using beam elements under tension-compression

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

The increasing demand for housing in Colombia and several neighboring countries, together with the large relative cost of the materials, has prompted city administrations to build thin reinforced concrete (RC) wall buildings with a single layer of reinforc ...

A Discrete Element Model for Predicting Shear Strength and Degradation of Rock Joint by Using Compressive and Tensile Test Data

Jian Zhao, Tohid Kazerani

A discrete element model is proposed to examine rock strength and failure. The model is implemented by UDEC, which is developed for this purpose. The material is represented as a collection of irregular-sized deformable particles interacting at their cohes ...

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 ...

Under strong earthquake motions, the liquid stored within large unanchored steel tanks can cause rocking and uplift of the tank base from the supporting foundation. Repeated rocking can lead to low-cycle fatigue fractures in the tank base-plate, and ultima ...

Effects of non-uniform strains on tensile fracture of fiber-reinforced ceramic composites

Varun Parameswaran Rajan

Effects of non-uniform strains on tensile fracture of fiber-reinforced ceramic–matrix composites have not been satisfactorily explained by existing mechanics-based models. In this paper, we use an exact model of fiber fragmentation under global load sharin ...

Electron Microscopy Mechanical Testing of Silicon Nanowires Using Electrostatically Actuated Tensile Stages

Reymond Clavel, Johann Michler, Jean-Marc Breguet, Dongfeng Zhang

Two types of electrostatically actuated tensile stages for in situ electron microscopy mechanical testing of 1-D nanostructures were designed, microfabricated, and tested. Testing was carried out for mechanical characterization of silicon nanowires (SiNWs) ...

Mechanical behaviour of diamond reinforced metals

Ludger Weber, Reza Tavangar Hamzehkolaei

Diamond reinforced metals with a diamond content of 55-60 vol.% were made by gas driven liquid metal infiltration. They were characterized with regard to their stiffness, strength and fracture toughness as a function of diamond particle size and matrix all ...
