Mechanical behaviour of a high explosive: multiaxial loading and strain-induced anisotropy

International audienceSome experimental tests have highlighted a strain-induced anisotropy on a TATB-based PBX. In order to understand the phenomenon, literature is studied. Two interpretations seem possible: an anisotropic damage or a behaviour mainly governed by a kinematic hardening. Several experiments carried out let think that the material strain-induced anisotropy is due to the latter
