High Strength Steel (HSS) characterization for numerical simulation of defence applications: from data collection to triaxiality model validation

Autor: Mespoulet Jerome, Habdulhamid Hakim, Deconinck Paul

Publikováno v: EPJ Web of Conferences, Vol 250, p 04003 (2021)

This paper details the methodology developed to fit a material strength/failure model with mesh sensitivity, strain rate influence and triaxiality effect on plastic failure for a blast/ballistic configuration for a HSS plate. Data collection in diffe

Characterization of the texture of large hailstones

Autor: Montagnat, Maurine, Bourcier, Mathieu, Philip, Armelle, Bons, Paul, Bauer, Catherine, Deconinck, Paul, Hereil, Pierre

Hailstone structures have been studied for over a century, but so far mainly by manual optical means. This paper presents new texture and microstructure data (i.e. crystal lattice orientations, grain sizes and shapes) measured with an Automatic Ice T
