Publikováno v: Procedia Structural Integrity. 2:3491-3500

In the particular case of welded structures, the tearing resistance is strongly dependent on the mismatch of welded joint. In this context, the fracture behavior of an undermatched electron beam (EB) welded joint on thick plate of aluminum alloy 6061

Assessment of the defect stability for large structures submitted to thermal shock loading through the Gfr criterion

Autor: Stéphane Marie, Stéphane Chapuliot, Olivier Ancelet

Publikováno v: International Journal of Pressure Vessels and Piping. 182:104066

This paper proposes a formulation and a numerical protocol to allow the application of the Gfr criterion for thick stainless steel components submitted to thermal shock loading. In a first part of the paper, a short description of the criterion initi
