The Challenge
Multiple site damage is a challenge to aerospace manufacturers as they need to demonstrate that designs satisfy safety requirements.
The Solution
This example performed as part of a research project with University partners aimed to investigate how multiple site damage could be predicted in built up structures including the effect of non linear contact behavior of the fasteners, load redistribution as the cracks grow and crack interaction.
The Value
Computer models can be used to reduce the number of tests which have to be performed and to provide data on how cracks will impact on the life of the structure. Data from models can also be used to build up design rules and databases.
