摘要
Abstract
The meso-damage evolution behavior of composite solid propellant is summarized.The research progress of meso-damage evolution of composite solid propellants is reviewed from three main aspects:the characterization method of meso-damage evolution,the finite element numerical simulation of meso-damage evolution and the viscoelastic constitutive model with damage.The shortcomings of current research and future research directions are pointed out.It was indicated that in the microscopic characterization aspect,it is difficult to realize the meso-damage characterization analysis under dynamic and com-plex loads,and new micro-scopic characterization methods need to be developed to improve the dynamic multi-scale observa-tion means to solve the problem of quantitative damage characterization.In the numerical simulation aspect,the two-dimen-sional RVE model and the interface model only applicable to a single load cannot reflect the real meso-damage evolution,and a three-dimensional RVE model,which can reflect the mesoscopic structure,and an interface model considering the effects of temperature and strain rate need to be established to obtain the accurate mesoscopic damage evolution process of propellant.In terms of constitutive model with damage,most of the phenomenological based constitutive models are unable to reflect the im-pact of mesoscopic structural changes on the mechanical response.A macroscopic and mesoscopic constitutive model needs to be developed to predict the mechanical response of propellant at mesoscopic scale.73 References are attached.关键词
