| Abstract: |
| A calculation model of shear bands is proposed in this paper to describe the formation and development of the shear bands in viscoplastic materials, such as explosives, when they are acted by Combined Compression-shear Loads. The calculation results in a further recognization of the shear bands. Further more, the relationship between variation features of the shear bands and initiation of the explosives are discussed. |
