Because the propellant grain is viscoelastic material, the liner and adiabatic layer are also viscoelastic one, the interface debond problem is actually interface crack about elastic - viscoelastic or bi - viscoelastic materials. research about this problem relates to the knowledge of viscoelastic mechanics and interface fracture and combustion. numerical analysis method about interface debond on solid rocket motor is researched in this paper
由於固體火箭發動機的推進劑藥柱是一種粘彈性材料，襯層和絕熱層也具有粘彈性性質，因此其界面脫粘問題實際上是彈性-粘彈性或雙粘彈性各向同性材料界面裂紋問題，對該問題的研究涉及到粘彈性力學、界面斷裂力學和燃燒學等相關學科。 -
First, the dynamic stability of braid composite cylindrical shells with the influences of some main factors is introduced. the general governing equations for the nonlinear dynamic stability is obtained. by the hamilton principle. the creep buckling analysis of braid composite cylindrical shells under axial compression and the dynamic stability under nonconservation force are discussed as emphases. in creep buckling question, by means of theoretical analysis, the instaneous critical load and durable critical load of viscoelastic braid composite cylindrical shell under axial compression are obtained and the numerical example is given
首先介紹了編織復合材料圓柱殼在幾種主要因素影響下的動力穩定性問題，用hamilton原理建立非線性動力穩定性問題的一般性基本方程。然後重點討論了編織復合材料圓柱殼軸壓下的蠕變屈曲問題及非保守力作用下的屈曲問題。對蠕變屈曲問題，通過理論分析來得到了編織復合材料圓柱殼的瞬時彈性臨界載荷和持久臨界載荷，給出了具體的算例。
