New model materials made of laser drilled copper sheets have been fabricated to study the ductile fracture process. In‐situ tensile tests in a scanning electron microscope and in an X‐Ray computed tomography set‐up allows us to observe the void growth and coalescence in 2D and 3D. It is shown that there are different modes of coalescence depending on the voids geometry and that constraining effects in the 3D case allow more void growth prior coalescence.
