Criticality in Fiber Bundle Model

Subhadeep Roy, Purusattam Ray

We report a novel critical behavior in the breakdown of an equal load sharing fiber bundle model at a dispersion $δ_{c}$ of the breaking threshold of the fibers. For $δ < δ_{c}$ , there…

Nucleation versus percolation: Scaling criterion for failure in disordered solids

Soumyajyoti Biswas, Subhadeep Roy, Purusattam Ray

One of the major factors governing the mode of failure in disordered solids is the effective range $R$ , over which the stress field is modified following a local rupture event. In…

$A + A \to \emptyset$ model with a bias towards nearest neighbor

Parongama Sen, Purusattam Ray

We have studied $A + A \to \emptyset$ reaction-diffusion model on a ring, with a bias $ε$ $(0 \leq ε \leq 0.5)$ of the random walkers $A$ to hop towards their nearest neighbor…
