Propagation of a Radial Fluid-driven Fracture in Nonlinear Solid --around the tip of a fluid-driven fracture: process zone vs deviated fluid flow

Brice Tanguy Alphonse Lecampion, Dong Liu

Deviations from conventional hydraulic fracturing simulators’ predictions are sometimes observed in the field and laboratory. This questions the basic assumptions adopted in linear hydraulic fracture mechanics (LHFM): a linear elastic solid and a simplifie ...

Shock waves produced by the interaction of dynamic crack with heterogeneities

Jean-François Molinari, Fabian Barras

Recent experiments reveals how dynamic fracture is characterized by the interplay of crack front with microscopic material heterogeneities. Heterogeneous dynamic fracture remains a current challenge both for numerical modeling and experiments because of th ...

The influence of through-thickness reinforcement geometry and pattern on delamination of fiber-reinforced composites: Part I - Experimental results

Véronique Michaud, John Botsis, Georgios Pappas

This experimental study reports effect of tuft geometry i.e., standard tufts and loops milled-down, and tufting pattern on Mode I interlaminar fracture in a GFRP. Standard tufting geometry is responsible for an increase in fracture resistance by 3.5-6 time ...

How Supertough Gels Break

John Martin Kolinski

Fracture of highly stretched materials challenges our view of how things break. We directly visualize rupture of tough double-network gels at >50% strain. During fracture, crack tip shapes obey a x similar to y(1.6) power law, in contrast to the parabolic ...

A mechanically-based model of snow slab and weak layer fracture in the Propagation Saw Test

Johan Alexandre Philippe Gaume, Lorenzo Benedetti

Dry-snow slab avalanche release is the result of failure initiation in a weak snowpack layer buried below a cohesive snow slab, which is then followed by rapid crack propagation. The Propagation Saw Test (PST) is a field experiment which allows to evaluate ...

Supershear bursts in the propagation of a tensile crack in linear elastic material

Jean-François Molinari, Fabian Barras, René Carpaij

Since the early years of the linear elastic theory of fracture [linear elastic fracture mechanics (LEFM)], scientists have sought to understand and predict how fast cracks grow in a material or slip fronts propagate along faults. While shear cracks can tra ...

Cyclic loading of a cellulose/hydrogel composite increases its fracture strength

Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss

The fracture properties of hydrogels which present similar characteristics to the Mullins effect is expected to decrease under repeated cyclic loading. Therefore, we assessed how cyclic loading affects the fracture behavior, the distribution of strain fiel ...

Unraveling Brittle-Fracture Statistics from Intermittent Patterns Formed During Femtosecond Laser Exposure

Yves Bellouard, Max-Olivier Hongler, Christos Edouardos Athanasiou

Femtosecond-laser-written patterns at the surface of brittle materials may show at random times spontaneous alternations from regular to disordered structures and vice versa. Here, we show that these random transitions carry relevant statistical informatio ...

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 ...
