摘　　要：研究了在压剪加载下炸药这类粘塑性介质中剪切带的形成与发展。提出了一种反映炸药装药中剪切带形成和发展的计算方法。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.
