Methods For The Design, Quality Control, And Management Of Fatigue-Limited Metal Components

US Patent:

56256647, Apr 29, 1997
Filed:

Oct 11, 1995
Appl. No.:

8/540876
Inventors:

Stanley G. Berkley - Jupiter FL
Assignee:

Fatigue Management Associates LLC - Palos Verdes CA
International Classification:

G01N 2320
US Classification:

378 72
Abstract:

Improved methods for managing a population of metal components subject to fatigue failure are provided. The residual compressive stress in the critical surfaces of such components, especially in areas of high stress concentration, are measured non-destructively using x-ray diffraction techniques. The measured surface residual compressive stress is used as a management criterion. A component having a surface residual compressive stress greater than a predetermined value can be returned to service. However, once the measured surface residual compressive stress of a component falls below the predetermined value, it can either be removed permanently from service, or it can be reworked to increase its surface residual compressive stress and then returned to service. Additionally, by measuring the surface residual compressive stress of an individual component, the remaining service life of that individual component can be estimated. These methods for management of populations of such metal components allow for increasing the service life of the components in a safe and effective manner.
