This paper presents a mechanical and numerical approach to model localized deformations occurring in concrete structures with less than minimum reinforcement. The presented models are based on, validated against large-scale experiments conducted previous study investigate the behavior of minimally reinforced slab framework structural safety assessment an existing cut cover tunnel. deploys rotat...

An infinite elastic medium with a planar crack is considered. The crack is subjected to the pressure of fluid injected at a point on the crack surface. Description of the crack growth is based on the lubrication equation (balance of the injected fluid and the crack volume), the equation for crack opening caused by fluid pressure on the crack surface, the Poiseuille equation related local fluid ...

The aim of the present paper is a systematic elab1 oration of a three dimensional finite element analysis tool for 2 discontinuous fracture in brittle solids. Brittle or quasi-brittle 3 fracture usually occurs when a material reaches the limit of its 4 strength and no plastic deformation has been observed prior 5 to failure. In the present approach, this kind of failure is char6 acterized by th...

Atomic Force Microscope images of a crack intersecting the free surface of a glass specimen are taken at different stages of subcritical propagation. From the analysis of image pairs, it is shown that a novel Integrated Digital Image Correlation technique allows to measure stress intensity factors in a quantitative fashion. Image sizes as small as 200 nm can be exploited and the surface displac...

phenomena, overstating the need for simulational tools that can handle multiple space and time scales is hard. The capability of addressing problems across several length and time scales is a hallmark of modern computational science, the goal of which is to tackle issues that straddle various traditional disciplines of science and engineering. Some interesting examples of such phenomena that ha...
