Three-dimensional buoyant hydraulic fractures: finite volume release

Brice Tanguy Alphonse Lecampion, Andreas Möri

In impermeable media, a hydraulic fracture can continue to expand even without additional fluid injection if its volume exceeds the limiting volume of a hydrostatically loaded radial fracture. This limit depends on the mechanical properties of the surround ...

Time-lapse reconstruction of the fracture front from diffracted waves arrivals in laboratory hydraulic fracture experiments

Brice Tanguy Alphonse Lecampion, Dong Liu, Thomas Emmanuel Blum

4-D acoustic imaging via an array of 32 sources/32 receivers is used to monitor hydraulic fracture (HF) propagating in a 250 mm cubic specimen under a true-triaxial state of stress. We present a method based on the arrivals of diffracted waves to reconstru ...

Influence of curved delamination front on R-curve of DCB specimen

Thomas Keller, Anastasios Vassilopoulos, Zhengwen Jiang

This work investigated the evolution of the non-uniform distribution of Mode-I strain energy release rate (SERR) along a straight pre-crack front of double cantilever beams (DCB), caused by the anticlastic deformation and the longitudinal free-edge effects ...

Post-Tensioned Structural Glass Beams - Comparative Experimental Study

Pieter Christian Louter, Jagoda Cupac

This paper presents a study of a system of post-tensioned structural glass beams. In order to increase the initial fracture strength of glass beams and provide residual load-carrying capacity in the event of glass failure, annealed laminated glass beams ar ...

Injectable calcium phosphate cement for augmentation around cancellous bone screws. In vivo biomechanical studies

Dominique Pioletti, Vincent Stadelmann

In lower cancellous apparent bone density, it can be difficult to achieve adequate screw fixation and hence stable fracture fixation. Different strategies have been proposed, one of them is through augmentation using calcium phosphate cement in the region ...

Bone regeneration and stem cells

Dominique Pioletti

This invited review covers research areas of central importance for orthopaedic and maxillofacial bone tissue repair, including normal fracture healing and healing problems, biomaterial scaffolds for tissue engineering, mesenchymal and foetal stem cells, e ...

Calcium phosphate cement augmentation of cancellous bone screws can compensate for the absence of cortical fixation

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

An obvious means to improve the fixation of a cancellous bone screw is to augment the surrounding bone with cement. Previous studies have shown that bone augmentation with Calcium Phosphate (CaP) cement significantly improves screw fixation. Nevertheless, ...
