| Abstract: | In this paper, dynamic response of the filler and reaction between the filler and projectile body are investigated. A more precise model for the calculation is set up in which the filler is under unilateral normal constraint from the rigid projectile wall and the property of the filler is expressed by linear viscoelastic- or linear elasti-constitutive laws. Viscoelasticity of the material, relative slide of the filler and the friction between the filler and the projectile body, etc., are considered. Dynamic and quasi-static solutions are finally evaluated through FEM. |
