Propellant and cover layer were assumed to be isotropic viscoelastic material (see Ref. [2]), whose young modulus is 29.43467MPa, Poisson's ratio is 0.499, and density is 1700kg /m3.
Then the two materials will debond, the burning surface will increase, the combustion pressure will be large enough to explode.
