It has recently been clarified that ductile fracture in aluminum alloys occurs predominantly through coalescence of hydrogen micropores. This type of ductile fracture was investigated by the image-based finite element analysis using the 3D image taken by X-ray tomography. The studied FE model consists of Al_2Cu particles and pores. The analysis revealed the distribution of local stress, strain and the stress triaxiality developed within the real material's structure, providing important clues to anticipate the location that would undergo significant damage.
