Density hardening plasticity and mechanical aging of silica glass under pressure: A Raman spectroscopic study
Damien Vandembroucq, Thierry Deschamps, Camille Coussa +4
In addition of a flow, plastic deformation of structural glasses (in particular amorphous silica) is characterized by a permanent densification. Raman spectroscopic estimators are…
Path independent integrals to identify localized plastic events in two dimensions
Mehdi Talamali, Viljo Petäjä, Damien Vandembroucq +1
We use a power expansion representation of plane elasticity complex potentials due to Kolossov and Muskhelishvili, to compute the elastic fields induced by a localized plastic defo…
Crack propagation through phase separated glasses: effect of the characteristic size of disorder
Davy Dalmas, Anne Lelarge, Damien Vandembroucq
We perform fracture experiments on nanoscale phase separated glasses and measure crack surface roughness by atomic force microscopy. The ability of tuning the phase domain size by…
Quantitative AFM analysis of phase separated borosilicate glass surfaces
Davy Dalmas, Anne Lelarge, Damien Vandembroucq
Phase separated borosilicate glass samples were prepared by applying various heat treatments. Using selective chemical etching we performed AFM measurement on the phase separated g…
Frozen capillary waves on glass surfaces: an AFM study
Thomas Sarlat, Anne Lelarge, Elin Sondergard +1
Using atomic force microscopy on silica and float glass surfaces, we give evidence that the roughness of melted glass surfaces can be quantitatively accounted for by frozen capilla…
Material-independent crack arrest statistics: Application to indentation experiments
Yann Charles, François Hild, Stéphane Roux +1
An extensive experimental study of indentation and crack arrest statistics is presented for four different brittle materials (alumina, silicon carbide, silicon nitride, glass). Evi…
Laplacian transfer across a rough interface: Numerical resolution in the conformal plane
Damien Vandembroucq, Stéphane Roux
We use a conformal mapping technique to study the Laplacian transfer across a rough interface. Natural Dirichlet or Von Neumann boundary condition are simply read by the conformal…
Light scattering from cold rolled aluminum surfaces
Damien Vandembroucq, Annie Tarrats, Jean-Jacques Greffet +2
We present experimental light scattering measurements from aluminum surfaces obtained by cold rolling. We show that our results are consistent with a scale invariant description of…
Material independent crack arrest statistics
Yann Charles, Damien Vandembroucq, Francois Hild +1
The propagation of (planar) cracks in a heterogeneous brittle material characterized by a random field of toughness is considered, taking into account explicitly the effect of the…
Effective toughness of heterogeneous brittle materials
Stephane Roux, Damien Vandembroucq, Francois Hild
A heterogeneous brittle material characterized by a random field of local toughness Kc(x) can be represented by an equivalent homogeneous medium of toughness, Keff. Homogenization…
Raman microspectroscopic characterization of amorphous silica plastic behavior
Antoine Perriot, Valérie Martinez, Laurent Grosvalet +4
Raman microspectroscopy was used to characterize amorphous silica plastic behavior. Using a correlation between Raman spectrum and density, a map of the local residual indentation-…
Conformal Mapping on Rough Boundaries II: Applications to bi-harmonic problems
Damien Vandembroucq, Stephane Roux
We use a conformal mapping method introduced in a companion paper to study the properties of bi-harmonic fields in the vicinity of rough boundaries. We focus our analysis on two di…
Large scale numerical simulations of "ultrametric" long-range depinning
Damien Vandembroucq, Stephane Roux
The depinning of an elastic line interacting with a quenched disorder is studied for long range interactions, applicable to crack propagation or wetting. An ultrametric distance is…
