In this work the output from a galvanic model is used to determine the spatial distribution of corrosion damage; providing a guide for the location of a corrosion representative initial flaw, that can be analyzed using stress fields from a structural model. In order to build confidence in this approach the galvanic model is first validated by comparing predicted results to surface damage measurements obtained from specimens used in an atmospheric exposure test program. Good comparison between the predicted spatial distribution of corrosion damage and the surface damage profiles obtained from the galvanic specimens is achieved. Following validation the galvanic damage map is then used to locate, and size, a crack at the edge of a fastener hole. Using this corrosion representative initial flaw, the stress intensity factor solution for a realistic fastener loading is determined.
In this webinar you will learn:
• The benefits of using an atmospheric corrosion model to identify areas of high galvanic stress
• A key corrosion metric used to validate an atmospheric corrosion model
• Ideas on sizing and locating an initial flaw using a galvanic stress map
• How to find the stress intensity factor solution for corrosion representative flaw at the edge of a mechanically loaded fastener
