| Abstract: |
| Using a three-dimensional model, quasi--atatic responses of thermo-viscoelastic grainsin solid rocket motors are analyzed under cure cooling, internal pressure and acceleration, so as to givea reference to the designer of actual structures. |
| Key words: Solid propellant rocket engine Solid propellant Viscoelasticity Finite element method |
