Abstract: A reasonable model of plastic bonded exploisve（PBX） substantiated by creep property is useful for finite element simulation of machining PBX components.Modified time hardening theoretical（MTHTT） model,which has compact form and less undetermined parameters,is promoted in this paper to describe creep behavior of PBX.A HMX based PBX is employed to conduct compressive creep tests.The model parameters are determined and the corresponding fitting details are discussed for validating the model.Meanwhi... More
