Numerical modelling of dynamic ductile fracture propagation in different lab-scale experiments using GTN damage model

Benoît Paermentier, Dimitri Debruyne, Reza Talemi

Initiation and propagation of ductile fractures are a major consideration during the design of high-pressure pipelines. Consequences of a pipeline failure can be catastrophic thus structural integrity must be ensured over several decades.…

A consistent use of the Gurson-Tvergaard-Needleman damage model for the R-curve calculation

Gabriele Cricrì

The scope of the present work is to point out a consistent simulation procedure for the quasi-static fracture processes, starting from the micro-structural characteristics of the material. To this aim, a local nineparameters…
