Observation of double percolation transitions in Ag-SnO$_2$ nanogranular films
, 2013 Two percolation transitions are observed in Ag$_x$(SnO$_2)_{1-x}$ nanogranular films with Ag volume fraction $x$ ranging from $\sim$0.2 to $\sim$0.9. In the vicinity of each percolation threshold $x_{ci}$ ($i$$=$1, 2), the variation in $\sigma$ with $x ...

Limit shapes for growing extreme characters of $U(\infty)$
, 2015 We prove the existence of a limit shape and give its explicit description for certain probability distribution on signatures (or highest weights for unitary groups).

Crack initiation and propagation in small-scale yielding using a nonlocal GTN model
, 2020 This study aims at investigating a non-local Gurson-Tvergaard-Needleman (GTN) ductile damage model at finite strains within the framework of small-scale yielding. This model solves the problems of spurious strain localization and volumetric locking.

Ductile failure analysis of high strength steel in hot forming based on micromechanical damage model
MATEC Web of Conferences, 2016 The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters.

Observation of SLE$(\kappa,\rho)$ on the Critical Statistical Models
, 2011 Schramm-Loewner Evolution (SLE) is a stochastic process that helps classify critical statistical models using one real parameter $\kappa$. Numerical study of SLE often involves curves that start and end on the real axis.

Ductile fracture simulations using a multi-surface coupled damage-plasticity model [PDF]
, 2017 In this paper, an isotropic porous metal plasticity model accounting for both void growth by diffuse plastic deformation and void ‘coalescence’ by localization of plastic flow in the inter-void ligaments is presented.
