A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Statistical Physics of Structural Glasses

open access: yes, 2000
This paper gives an introduction and brief overview of some of our recent work on the equilibrium thermodynamics of glasses. We have focused onto first principle computations in simple fragile glasses, starting from the two body interatomic potential.

Configurational Entropy in k-mer Adsorption

open access: yesLangmuir, 2000
The general basis for accurate calculations of k-mer lattice gases' configurational entropy is presented. The method relies on the definition of an artificial Hamiltonian from the system of interest. By Monte Carlo calculation of mean total energy followed by thermodynamic integration from a reference state of the artificial Hamiltonian, the entropy of

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Splitting up entropy into vibrational and configurational contributions in bulk metallic glasses: A thermodynamic approach

open access: yesPhysical Review Research, 2020
We apply an efficient methodology to separate vibrational and configurational entropies in bulk metallic glasses by means of molecular dynamics simulation based on a combination of nonequilibrium adiabatic switching and reversible scaling methods.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Non-Extensivity of the Configurational Density Distribution in the Classical Microcanonical Ensemble

open access: yesEntropy, 2009
We show that the configurational probability distribution of a classical gas always belongs to the q-exponential family. One of the consequences of this observation is that the thermodynamics of the configurational subsystem is uniquely determined up to ...

The role of structure and entropy in determining differences in dynamics for glass formers with different interaction potentials

open access: yes, 2014
We present a study of two model liquids with different interaction potentials, exhibiting similar structure but significantly different dynamics at low temperatures.
