Residual stress measurements on Ti6Al4V samples produced by additive manufacturing with an integrated structural health monitoring system
The objective of this work is to measure residual stresses on Additive Manufacturing (AM) Ti6Al4V samples produced by laser metal deposition with an integrated structural health monitoring system. It is important to mention that there have been no previous neutrons measurements on that kind of samples. This work is a part of a research project funded by an SBO Project of the Agency for Innovation by Science and Technology (IWT) of Belgium, where a new concept, the so-called effective structural health monitoring (eSHM) system has developed. The basic physical principle of the system is checking the absolute fluid pressure changes in a 3D network of capillaries or cavities that are integrated with AM techniques in the interior of a part made by AM. A pressure change in the capillary indicates the presence of a crack. Within this project, the residual stresses of 4-point-bending fatigue samples will be measured and compared with FE simulations results by other collaborators of the project. Furthermore, the samples will be subjected in 4-point-bending fatigue tests.
