“…Considerable efforts were made within the scientific community for determination of an intrinsic criterion for fracture toughness assessment of ductile materials (Bensaada et al, 2018;Wang et al, 2013). It has been recognized that the fracture mechanical parameters are dependent on the geometric parameters of tested specimens (Brocks et al, 2010).…”

The aim of the study is to assess the constraint effect induced by variation of geometric parameters on fracture toughness of stainless steel 304L thin sheets. A combined experimental-computational method is used. Compact Tension (CT) tests are firstly done using a special device realized to avoid buckling problems. Finite element analysis is used including the GTN (Gurson-Tvergaard-Needleman) model based on micromechanical assumptions of ductile fracture to obtain crack propagation. The fracture toughness is evaluated using an incremental formulation of the J-Integral. The results obtained show a quantified dependency of the critical fracture toughness on the constraint effect.
