| Abstract: |
| The transient temperature distribution in a solid rocket motor grain during its curingprocess is calculated with three dimensional finite element method. Based on the viscoelastic integralconstitutive relation, a thermal stress field in the grain is calculated, and the calculating program maybe used in engineering practice. |
| Key words: Solid propellant rocket engine Propellant grain Temperature distribution Stress distribution Finite element method |
