In Situ Laminography Investigation of Damage Evolution in S355 Base Material

The ARAMIS system introduced in the previous chapter has been used monitoring the crack propagation for the C(T)-specimen extracted from the S355 base material. The ARAMIS system allows only observing crack propagation at the surface of the object, the evolution of void initiation, growth and coalescence inside the material remains unknown. In order to understand the 3D damage evolution and to show the nature of crack propagation during the material deformation process, it is necessary to adopt a technique to display the imaging of the damage.
