Crack formation in composites through a spring model
Sadhukhan, Supti; Dutta, Tapati; Tarafdar, Sujata - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 4, pp. 731-740
When two or more different materials are combined to form composites, the property of the composite may be quite …. We study crack formation in composites through a very general spring network model on a square lattice. The spring model …

Micro-foundation using percolation theory of the finite-time singular behavior of the crash hazard rate in a class of rational expectation bubbles
Seyrich, Maximilian; Sornette, Didier - 2016
crash hazard rate in the Johansen-Ledoit-Sornette model of rational expectation bubbles. The model is based on a percolation … crash. This provides a formula to estimate the crash hazard rate by summation over percolation clusters above a minimum size … of a power $s^a$ (with $a>1$) of the cluster sizes $s$, similarly to a generalized percolation susceptibility.The power …

Computer simulation of fractal growth via a 2D-MECA percolative system representing an extended nutrient releasing source (NRS)
Helali, N.; Rezig, B. - In: Physica A: Statistical Mechanics and its Applications 292 (2001) 1, pp. 9-25
Monte Carlo simulations are investigated to study the effects of the nutrient releasing source (NRS) on fractal patterns developed by a generalized dynamic fractal growth model (GDFGM). The morphology of the simulated structures reveals, in cylinder geometry, a strong correlation with the source...
