New Book Released on Fatigue at High Temperatures
September 26, 2009 – 2:31 pm
A book entitled “Fatigue and Durability of Metals at High Temperatures” is now available through ASM [External Link]. This book is the second of a two-part series written by former R&T Structures Division personnel Drs. Gary Halford and Stan Manson. This book covers analysis of time-dependent metal fatigue at high temperatures. The work describes the effect of creep deformation on fatigue life.
The GRC-developed lifing scheme of strain-range partitioning is described, and used to assess fatigue life for different deformation conditions and multi-axial loads. Methods for predicting time-dependent fatigue are critiqued, and aerospace examples illustrate applications. The body of this work culminates the professional careers of Drs. Halford and Manson and their major contributions to the area of high temperature fatigue.
American Ceramic Society Recognition Given in ACerS Bulletin
September 19, 2009 – 1:42 pm
Dr. Alp Sehirlioglu (Ceramics Branch/RXC/CWRU) was recognized in the September 2009 issue of the American Ceramic Society’s (ACerS) Bulletin as an inaugural Council member and Recognition and Awards Action Team member of the newly established Young Professionals Network (YPN).
This Council consists of people from industry, academia, and national laboratories. The purpose of ACerS Young Professionals Network is to enable the Society to better attract, engage, and serve materials professionals in the first ten years of their careers.
Awards Received from CEV Thermal Protection System Advanced Development Project
September 19, 2009 – 1:37 pm
As part of the Crew Exploration Vehicle (CEV) Thermal Protection System (TPS) Advanced Development Project (ADP), researchers from the Tribology & Mechanical Components Branch Seal Team developed and evaluated a sealing system for the interface between the heat shield and the back-shell on Orion.
This effort included formulation of a design for the sealing system and subsequent testing of the seals at representative operating conditions. Compression, leakage, bond integrity, and thermal exposure tests were performed by the team on sub-scale seals at NASA Glenn Research Center.
Glenn also conducted extensive arc jet tests at NASA Ames Research Center using a unique test fixture that simulated reentry heating conditions on the interface. These tests demonstrated the ability of the GRC seals to prevent ingress of hot re-entry gases into the heat shield to the back-shell interface.
For their contributions and commitments in leading this effort at GRC, Bruce Steinetz and Pat Dunlap were honored by the CEV Project Office and CEV TPS ADP during a ceremony on September 10, 2009 at NASA Ames. Dr. Pete Worden, NASA Ames Center Director, presented the awards.

Goodyear Release Details Invention with NASA of Airless Spring Tire for Moon, Possibly Earth
August 10, 2009 – 3:49 pm
A Goodyear press release from August 3, 2o09, talks about how “NASA and The Goodyear Tire & Rubber Company have developed an airless tire to transport large, long-range vehicles across the surface of the moon.
“The new ‘Spring Tire’ with 800 load bearing springs is designed to carry much heavier vehicles over much greater distances than the wire mesh tire previously used on the Apollo Lunar Roving Vehicle (LRV). The new tire will allow for broader exploration and the eventual development and maintenance of a lunar outpost.
“According to Vivake Asnani, NASA’s principal investigator at the Glenn Research Center in Cleveland, this was a significant change in requirements that required innovation. ‘With the combined requirements of increased load and life, we needed to make a fundamental change to the original moon tire,’ he said.
“‘What the Goodyear-NASA team developed is an innovative, yet simple network of interwoven springs that does the job. The tire design seems almost obvious in retrospect, as most good inventions do.’”
