Porosity Measurements and Analysis for Metal Additive Manufacturing Process Control

September 16, 2014
Author(s)
John A. Slotwinski, Edward J. Garboczi, Keith M. Hebenstreit
Additive manufacturing techniques can produce complex, high-value metal parts, with potential applications as critical metal components such as those found in aerospace engines and as customized biomedical implants. Material porosity in these parts is

Application of a Natural Ventilation System Design Tool To A School Building

November 8, 2013
Author(s)
Steven J. Emmerich, William S. Dols, Brian J. Polidoro
A software tool to aid in the design of natural ventilation systems has recently been udpated. This update implements a general method for sizing of natural ventilation components, which allows direct consideration of stack and wind-driven airflow. The

Dynamic Analysis of Sliding Contacts at Head-Disk Interface

October 1, 2002
Author(s)
Tze J. Chuang, Stephen M. Hsu
As magnetic data storage technology moves towards higher areal data density with higher rotational speeds and lower flying heights, the propensity of severe sliding contacts at the head-disk interface is bound to increase. The tribological performance of
