Abstract
The effect of dynamic shear and tensile strength of tungsten heavy alloys on the fracture mode of fragmentation under explosive loading was investigated. The results show that the conclusion about the synthetic effect of stress state and material properties on fracture mode of tungsten alloy fragments which is analyzed using the stress state theory of fracture mechanics accords with experimental results. The ratio of tensile to shear strength can express the brittleness of tungsten alloys. Under explosive loading, the brittleness of tungsten alloys increases with the ratio falls, the probability of tensile fracture of fragment is increased linearly.
