WebICMR : International Center for Materials Research Home WebJan 1, 2024 · For each set of parameters, the simulations were repeated N 0 = 40 times, in order to explore the stochastic cross-slip mechanism. To demonstrate the probabilistic behavior of the simulations, we plot in Fig. 2 the fraction of simulations N/N 0 without cross-slip until time t, for an external stress of 1.1 GPa and a temperature of 525 K for different …
