Automation software for a materials testing laboratory
Author(s): Mcgaw, Michael A.; Bonacuse, Peter J.
Abstract: The software environment in use at the NASA-Lewis Research Center's High Temperature Fatigue and Structures Laboratory is reviewed. This software environment is aimed at supporting the tasks involved in performing materials ...

A high temperature fatigue life prediction computer code based on the Total Strain Version of Strainrange Partitioning (SRP)
Author(s): Mcgaw, Michael A.; Saltsman, James F.
Abstract: A recently developed high-temperature fatigue life prediction computer code is presented, based on the Total Strain version of Strainrange Partitioning (TS-SRP). Included in this code are procedures for characterizing the ...

Bithermal fatigue - A link between isothermal and thermomechanical fatigue
Author(s): Halford, Gary R.; Mcgaw, Michael A.; Bill, Robert C.; Fanti, Paolo D.
Abstract: A technique for bithermal fatigue testing is presented in which the tensile and compressive halves of the cycle are conducted isothermally at two significantly different temperatures. With reference to experimental results ...

Effect of tensile mean stress on fatigue behavior of single-crystal and directionally solidified superalloys
Author(s): Kalluri, Sreeramesh; Mcgaw, Michael A.
Abstract: Two nickel base superalloys, single crystal PWA 1480 and directionally solidified MAR-M 246 Hf, were studied in view of the potential usage of the former and usage of the latter as blade materials for the turbomachinery of ...

Cumulative creep-fatigue damage evolution in an austenitic stainless steel
Author(s): Mcgaw, Michael A.
Abstract: A model of cumulative creep-fatigue damage has been developed which is based on the use of damage curve equations to describe the evolution of creep-fatigue damage for four basic creep-fatigue cycle types. These cycle types ...
