摘要：

In the frame of the European ATLAS+ project it was decided to evaluate if a continuum damage model can simulate a four pointsbeading test on a ferritic pipe (A508 type). In this paper, the theoretical background is presented. Then, based on finite elements analyses, the GTN model damage parameters are defined by simulating laboratory tests on Notched Tensile specimens and Compact Tension specimens. From that identification, experimental tests on Single Edge Notched Tensile specimens are simulated in order to verb if the previous parameters are able to describe a large ductile tearing. Finally, the four points bending test simulation is also presented.
