Rapid Production of Accurate Embedded-Atom Method Potentials for Metal Alloys

A critical limitation to the wide-scale use of classical molecular dynamics for alloy design is the limited availability of suitable interatomic potentials. Here, we introduce the Rapid Alloy Method for Producing Accurate General Empirical Potentials or RAMPAGE, a computationally economical procedure to generate binary embedded-atom model potentials from already-existing single-element potentials that can be further combined into multi-component alloy potentials. We present the quality of RAMPAGE calibrated Finnis-Sinclair type EAM potentials using binary Ag-Al and ternary Ag-Au-Cu as case studies. We demonstrate that RAMPAGE potentials can reproduce bulk properties and forces with greater accuracy than that of other alloy potentials. In some simulations, it is observed the quality of the optimized cross interactions can exceed that of the original off-the-shelf elemental potential inputs

Brownwood Comprehensive Plan 2012

The City of Brownwood‘s Comprehensive Plan is the chief tool to enable the management of growth and the delivery of public services in a timely and efficient manner.Three courses were devoted to the assessment of past and current community conditions and made recommendations of projected growth in the following areas: economic development, housing, land use mapping, zoning mapping, transportation and infrastructure, and facilities management.Texas Target COmmunitie
