Abstract:
In order to study the viscoelastic behavior of solid propellants,based on the hereditary integral forms of the viscoelastic Poisson's ratio expression and combined with the Laplace transformation and creep test conditions,the accurate Poisson's ratio expression of the propellant material is deduced with the known transverse strain and relaxation modulus,and the corresponding program is compiled by Matlab.The corresponding creep test is designed to obtain the transverse strain of propellant materials.The change law between the Poisson's ratio and time of the propellant material is obtained based on the relaxation modulus.The results can provide input parameters for the structural integrity analysis of solid propellants.
