Stress-Strain Analysis of Composite Propellant under Cyclic Temperature Loads

Abstract:

Based on integral nonlinear viscoelastic constitutive relationship, stress-strain field was analyzed of composite propellant under cyclic temperature loads to ensure the stress-strain distribution and damageable locality. The simulation conditions were designed in the temperature range from-10 to 60 at three different rate-temperature. The results indicate that the stress and strain have the same trend of changing. Adhesive interphase is prone to failure because of the alternating stress.
