Role of the sample thickness in planar crack propagation
Pallab Barai, Phani K. V. V. Nukala, Mikko J. Alava +1
We study the effect of the sample thickness in planar crack front propagation in a disordered elastic medium using the random fuse model. We employ different loading conditions and…
Fracture strength of disordered media: Universality, interactions and tail asymptotics
Claudio Manzato, Ashivni Shekhawat, Phani K. V. V. Nukala +3
We study the asymptotic properties of fracture strength distributions of disordered elastic media by a combination of renormalization group, extreme value theory, and numerical sim…
Sub-matrix updates for the Continuous-Time Auxiliary Field algorithm
Emanuel Gull, Peter Staar, Sebastian Fuchs +5
We present a sub-matrix update algorithm for the continuous-time auxiliary field method that allows the simulation of large lattice and impurity problems. The algorithm takes optim…
A Fast and Efficient Algorithm for Slater Determinant Updates in Quantum Monte Carlo Simulations
Phani K. V. V. Nukala, P. R. C. Kent
We present an efficient low-rank updating algorithm for updating the trial wavefunctions used in Quantum Monte Carlo (QMC) simulations. The algorithm is based on low-rank updating…
Size effects in statistical fracture
Mikko J. Alava, Phani K. V. V. Nukala, Stefano Zapperi
We review statistical theories and numerical methods employed to consider the sample size dependence of the failure strength distribution of disordered materials. We first overview…
Anomalous Roughness of Fracture Surfaces in 2D Fuse Models
Phani K. V. V. Nukala, Stefano Zapperi, Mikko Alava +1
We study anomalous scaling and multiscaling of two-dimensional crack profiles in the random fuse model using both periodic and open boundary conditions. Our large scale and extensi…
