Abstract Scope |
The fracture initiation and propagation process in the corroded nuclear structure material when impact by a high-velocity blunt shaped projectile is simulated in the present research. The impact process results in the crack propagation and fragmentation in the target material. Additionally, the corrosion in the material degrades the overall mechanical and ballistic performance of the structures. The effect of corrosion in the material has also been analyzed. During impact, the target material undergoes large deformation, resulting in the evolution of the ductile damage and ultimately leading to the fracture. The fracture in the material is simulated using CDM at the velocity range of 200-600 m/sec. The effect of inherent voids evolved due to corrosion on the ballistic behavior has also been presented. It is found that the cracks propagate due to the presence of inherent voids in the target body. The corrosion degrades the ballistic performance of the target body. |
