Methods of Swanson Constitutive Model Establishment for Composite Solid Propellant

Abstract:

Establishing Swanson constitutive model is discussed for composite solid propellant, which focused on the calculation of strain softening function and change strain rate correction function within the model. Prediction results of Swanson constitutive model are in good agreement degrees with the test of 24 groups uniaxial tensile data of composite solid propellant at different temperatures and extension rates. It proves the model is effective and available.
