Abstract:To understand the mechanics of dewetting by accounting for the viscous nature of the material, the micromechanics of dewetting in solid propellant materials is analyzed at a unit cell containing a single particle imbedded in a linearly viscoelastic matrix. For weakly bonded particle/matrix interfaces, the energetics of dewetting are established and solutions for the dewetting stress are obtained under purely hydrostatic straining conditions. The dependence of the dewetting stress on the loading rate, particle size, and particle/matrix bond fracture energy is quantified.
