Fearless versus Fearful Speculative Financial Bubbles
J. V. Andersen, D Sornette
Using a recently introduced rational expectation model of bubbles, based on the interplay between stochasticity and positive feedbacks of prices on returns and volatility, we devel…
Scaling with respect to disorder in time-to-failure
D. Sornette, J. V. Andersen
We revisit a simple dynamical model of rupture in random media with long-range elasticity to test whether rupture can be seen as a first-order or a critical transition. We find a c…
New model for surface fracture induced by dynamical stress
J. V. Andersen, L. J. Lewis
We introduce a model where an isotropic, dynamically-imposed stress induces fracture in a thin film. Using molecular dynamics simulations, we study how the integrated fragment dist…
Tri-critical behavior in rupture induced by disorder
J. V. Andersen, D. Sornette, K. -T. Leung
We discover a qualitatively new behavior for systems where the load transfer has limiting stress amplification as in real fiber composites. We find that the disorder is a relevant…
