Significant elastic anisotropy in Ti$_{1-x}$Al$_x$N alloys [PDF]

open access: yes, 2002
Strong compositional-dependent elastic properties have been observed theoretically and experimentally in Ti$_{1-x}$Al$_x$ N alloys. The elastic constant, C$_{11}$, changes by more than 50% depending on the Al-content.

Graph and Analytical Models for Emergency Evacuation

open access: yesFuture Internet, 2013
Cyber-Physical-Human Systems (CPHS) combine sensing, communication and control to obtain desirable outcomes in physical environments for human beings, such as buildings or vehicles. A particularly important application area is emergency management. While

On Computational Modelling Of Strain-Hardening Material Dynamics [PDF]

open access: yesCommunications in Computational Physics, 2012
AbstractIn this paper we show that entropy can be used within a functional for the stress relaxation time of solid materials to parametrise finite viscoplastic strain-hardening deformations. Through doing so the classical empirical recovery of a suitable irreversible scalar measure of work-hardening from the three-dimensional state parameters is ...

Collisional dynamics around binary black holes in galactic centers [PDF]

open access: yes, 2001
We follow the sinking of two massive black holes in a spherical stellar system where the black holes become bound under the influence of dynamical friction. Once bound, the binary hardens by three-body encounters with surrounding stars.

Stability Properties of 1-Dimensional Hamiltonian Lattices with Non-analytic Potentials

open access: yes, 2020
We investigate the local and global dynamics of two 1-Dimensional (1D) Hamiltonian lattices whose inter-particle forces are derived from non-analytic potentials.

Discrete dislocation simulations and size dependent hardening in single slip [PDF]

open access: yes, 1998
Plastic deformation in two-dimensional monophase and composite materials is studied using a discrete dislocation dynamics method. In this method, dislocations are represented by line defects in a linear elastic medium, and their interactions with ...

Harnessing ferroic ordering in thin film devices for analog memory and neuromorphic computing applications down to deep cryogenic temperatures

open access: yesFrontiers in Nanotechnology
The future computing beyond von Neumann era relies heavily on emerging devices that can extensively harness material and device physics to bring novel functionalities and can perform power-efficient and real time computing for artificial intelligence (AI)

On Prediction of 3d Stress State in Elastic Shell by Higher-order Shell Formulations [PDF]

open access: yes, 2008
In this work we study the accuracy of modem higher-order shell finite element formulations in computation of 3d stress state in elastic shells. In that sense we compare three higher-order shell models: (i) with seven dislacement-like kinematic parameters,

Prognostic Impact of Treatment Modalities, Including Targeted Compartmental Radio‐Immunotherapy, in a Cohort of Neuroblastoma Patients With CNS Metastases at Relapse

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neuroblastoma (NB) with central nervous system (CNS) metastases is rare at diagnosis, but occurs more often during relapse/progression. Patients with CNS metastases face a dismal prognosis, with no standardized curative treatment available.

Computing in-situ strength of rock masses based upon RQD and modified joint factor: Using pressure and damage sensitive constitutive relationship

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2015
In this study, a new model was presented for computing strength of rock masses based upon in-situ observations of RQD popularly known as rock quality designation.
