Abstract

Ballistic resistant composites plays a major role in defence applications and development of such composites should be carefully assessed before being physically developed. The present study deals with development of conceptual proof for jute rubber based flexible composite block to completely arrest the projectile impacting the target at high velocity impact of 400 m/s using ABAQUS CAE 14.0 simulation software through finite element (FE) approach. The proposed target and the bullet are modelled as deformable and rigid bodies respectively. The mesh convergence study is carried out prior to performing the final simulation. The proposed flexible composite blocks are modelled with thickness of 30 to 120 mm with an increment of 30 mm to assess their bullet arresting behaviour. The results reveal that the proposed flexible composite with 90 mm just arrests the bullet. However, the damage propagates till the last layer of the composite. Considering safety concerns, the use of a 120 mm thick, compliant composite is recommended for development of compliant bullet resistant blocks. The results presented here may serve as benchmark for effective utilization of sustainable materials in development of composite blocks to resist ballistic impact loads. © 2022, The Author(s), under exclusive licence to Springer-Verlag France SAS, part of Springer Nature.
