K., Corporate Author: United States. National Aeronautics and Space Administration. Other Authors. For the stress analysis of the multiaxial cowl lip problem, a finite element model constructed by Melis and Gladden7 was utilized.

This model, shown inFigure 2, is made up of solid eight-noded brick elements and has nodes. The dimensions of the cowl lip are approximately 6 by by in. ( by by cm).

The aim of this study is to predict the life-limiting thermomechanical behavior of a large SPF tool under realistic forming conditions using elastic-plastic-creep FE analyses. Nonlinear time-dependent, sequentially coupled FE analyses are performed using temperature-dependent monotonic and cyclic material data for a high-nickel, high-chromium Cited by: 1.

The thermomechanical, time-dependent, elastic-plastic creep behaviour of a representative tool in a high-temperature superplastic forming press has been simulated using a sequential finite element. Material data representation of hysteresis loops for Hastelloy X using artificial neural networks.

Finite Element Elastic-Plastic- Creep and Cyclic Life flow, necessitating a nonlinear inelastic stress-strain analysis.

Elastic-plastic analysis. -The stress and strain results of an elastic-plastic analysis of the cowl lip problem are shown in Figures 7 and 8. Thermal Fatigue Analysis of Cast Aluminum Cylinder Heads The thermal fatigue of a cylinder head during such a start and stop cycle needs to be considered in engine design.

A complete thermo-mechanical fatigue analysis of a cast aluminum cylinder head should include both stress-strain determination and life prediction. Full text of "NASA Technical Reports Server (NTRS) Aeronautical engineering: A continuing bibliography with indexes (supplement )" See other formats.
