In an effort to bring some clarification on the vast literature on finite strain viscoelastic models, initially defined for elastomers, a review of the pioneering models on finite strain viscoelastic from Le Tallec et al. (1993), Lion (1997) and Reese and Govindjee (1998) has shown that these models are totally equivalent [1]. It is not […]

Impact of matrix/filler adhesion on properties on local damage and macroscopic behavior of propellants
With industrial partner Arianegroup, we studied the mechanical behavior of three propellant-like materials. Two materials were made of an inert matrix with about 55% of sifted 250 microns ammonium perchlorate (AP) or RDX particles. The last material was the polymer matrix filled with about 20% of aluminium 3 microns particles and filled with AP fillers. […]
