Abstract:
When shock waves propagate in solid mediums, the internal charge carriers migrate to the electrodes under the action of shock waves to form electric potential and output voltage/current -shock induced polarization (SIP) effect. The development of SIP...

Abstract:
Heterogeneous media are very common in nature. Due to the complex internal structure, the heterogeneous compressive shear coupled stress field is inside heterogeneous media, which leads to a mutual influence of compression and shear waves. The study ...

Abstract:
Under pure bending, a brittle slender beam may undergo sudden fracture, leading to the occurrence of secondary fractures near the initial fracture point. Studies suggest that the secondary fractures are induced by the unloading bending wave released ...

Abstract:
The stress-strain data obtained from split Hopkinson pressure bar (SHPB) tests include both strain rate effects and structural effects, where the structural effects result in non-uniform stress in the elastic phase of the stress-strain curve. The ela...
