Physical and chemical characterization techniques for metallic powders

August 28, 2013
Author(s)
John A. Slotwinski, Paul E. Stutzman, Stephanie S. Watson, Edward J. Garboczi, Max A. Peltz, Chiara F. Ferraris
Systematic studies have been done on two different powder materials used for additive manufacturing: stainless steel and cobalt-chrome. An extensive array of characterization techniques were applied to these two powders. The physical techniques included

Porosity of Additive Manufacturing Parts for Process Monitoring

July 26, 2013
Author(s)
John A. Slotwinski, Edward J. Garboczi
Some metal additive manufacturing processes can produce parts with internal porosity, either intentionally (with careful selection of the process parameters) or unintentionally (if the process is not well understood.) Material porosity is undesirable for

The Computational Materials Science of Concrete: Past-Present-Future

May 8, 2013
Author(s)
Edward Garboczi
From its small beginnings back in the 1960s, computational materials science has come a long way. The field is currently getting even more exciting with ideas like integrated computational materials engineering [1] being seriously considered in the start

Modeling of the Influence of Transverse Cracking on Chloride Penetration into Concrete

April 23, 2013
Author(s)
Dale P. Bentz, Edward J. Garboczi, Yang Lu, Nicos Martys, Aaron R. Sakulich, William J. Weiss
Concrete service life models have proliferated in recent years due to increased interest in designing infrastructure elements with at least a 75-year service life, along with greater emphasis on life cycle costing in general. While current models consider

Bridging the gap between random microstructure and 3-D meshing

November 10, 2012
Author(s)
Edward Garboczi, Yang Lu
There are different ways of mathematically representing 3-D heterogeneous material structures. But for each of these methods, usually the desired end result is a 3-D finite element mesh that will be used to investigate the mechanical properties of the

An Argument for Virtual Testing in the Cement Plant

September 10, 2012
Author(s)
Pichet Sahachaiyunta, Kittisak Pongpaisanseree, Jeffrey W. Bullard, Paul E. Stutzman, Edward Garboczi, Wilasa Vichit-Vadakan
The cement industry is moving toward customized commodity products, requiring plants that were built to consistently produce thousands of tons of one product each day to now be versatile enough to fine-tune multiple products that meet both industry

Elastic and Viscoelastic Properties of Calcium Silicate Hydrate

May 15, 2012
Author(s)
Zachary Grasley, Jones Christopher, X Li, Edward Garboczi, Jeffrey W. Bullard
In order to effectively predict the mechanical properties of concrete and other cementitious materials, it is useful to understand the properties and deformation mechanisms on the nano-metric length scale. Through a combined analytical, experimental, and
