The irreversible thermal expansion of an energetic material
Autor: Hervé Trumel, François Willot, Thomas Peyres, Maxime Biessy, François Rabette
Publikováno v: Journal of Theoretical, Computational and Applied Mechanics (2021)
The work deals with a macroscopically isotropic energetic material based on triamino-trinitrobenzene (TATB) crystals bonded with a small volume fraction of a thermoplastic polymer. This material is shown experimentally to display an irreversible ther
