【 摘 要 】

Finite element analysis of case-bonded solid propellants in finocyl port configuration has been carried out using finite element method. The parametric studies have also been conducted for loading conditions, material properties, and geometrical configurations. The results are presented in the form of a universal power law, which can be utilised for primary assessment of peak strain in any finocyl port propellant configuration without using finite element software. This eliminates dependence on finite element software for structural integrity analysis of solid propellants in finocyl port configuration under port pressurisation. The results obtained by finite element analysis and power law are in close agreement.
