- Abstract
- The objective of this study is to investigate the adiabatic shear band formation in 2124-T6 aluminum composites reinforced with SiC whiskers. The composites were deformed at high strain rates by ballistic impact. Adiabatic shear bands initiated from cracks near the impacted region were observed. The shear bands tended to propagate along the extrusion direction, since they were blocked by SiC whiskers. With the shear bands, microvoids and microcracks formed, presumably by the temperature rise. Shear bands, together with microvoids and microcracks, deteriorated the impact resistance of target materials. Finally, performance of the composites against ballistic impact loading was discussed by comparing the behavior of shear banding with dynamic fracture toughness.
