Dynamic damage modelling through phase-field approaches: assessment, critical analysis and comparison Open
This work assesses the ability of various phase field approaches to model dynamic damage evolution up to fracture. The damage evolution can be formulated using several types of Partial Differential Equations (PDEs), such as elliptic, parab…

Optimization of an Image-Based Experimental Setup for the Dynamic Behaviour Characterization of Materials Open
\n The present work aims at identifying an elastic-viscoplastic material constitutive model over a wide strain and strain-rate range (up to 0.1 and 1000 s \n −1\n respectively), using the so-called Virtual Fields Method. To define the expe…
