Multiple scattering of elastic waves by pinned dislocation segments in a continuum
Dmitry Churochkin, Felipe Barra, Fernando Lund +2
The coherent propagation of elastic waves in a solid filled with a random distribution of pinned dislocation segments is studied to all orders in perturbation theory. It is shown t…
Measuring Dislocation Density in Aluminum with Resonant Ultrasound Spectroscopy
Felipe Barra, Andres Caru, Maria Teresa Cerda +4
Dislocations in a material will, when present in enough numbers, change the speed of propagation of elastic waves. Consequently, two material samples, differing only in dislocation…
Conformal Dynamics of Precursors to Fracture
Felipe Barra, Mauricio Herrera, Itamar Procaccia
An exact integro-differential equation for the conformal map from the unit circle to the boundary of an evolving cavity in a stressed 2-dimensional solid is derived. This equation…
