IIT Madras Develops Advanced Ballistic Protection for RC Panels

IIT Madras Develops Innovative Framework to Enhance Ballistic Resistance in Critical Infrastructure

Researchers at IIT Madras have introduced a cutting-edge framework designed to enhance the ballistic resistance of reinforced concrete (RC) panels, crucial for securing critical infrastructure such as military bunkers, nuclear power plants, bridges, and runways. This new approach aims to strengthen these structures against ballistic missile threats, ensuring higher safety and durability.

Breakthrough in Ballistic Protection for Concrete Structures

Utilizing advanced Finite Element (FE) simulations, the research team examined the impact of missile strikes on RC panels, analyzing damage patterns such as penetration, spalling, and crushing caused by projectile impacts. Given the widespread use of reinforced concrete in high-security installations, this study provides valuable insights into improving their resistance against external threats.

The project, spearheaded by Dr. Alagappan Ponnalagu, Assistant Professor in the Department of Civil Engineering at IIT Madras, alongside research scholar Roouf Un Nabi Dar, introduces a performance-based ballistic design framework. This approach utilizes Depth of Penetration (DOP) calculations and a probabilistic model to estimate crater formation and structural damage with greater precision. Their findings have been published in the prestigious journal Reliability Engineering & System Safety.

Revolutionizing Ballistic Design with Advanced Methodologies

Dr. Alagappan emphasized the urgent need for enhanced ballistic-resistant design strategies to strengthen defense infrastructure in the face of evolving threats. He highlighted that conventional design methods depend on deterministic empirical formulas, which often yield inconsistent and unreliable results. The new probabilistic model developed by IIT Madras overcomes these limitations, providing a more precise and effective method for damage assessment.

"The importance of ballistic-resistant design in defense infrastructure cannot be overstated. While previous studies have examined local damage parameters, a comprehensive ballistic design philosophy was missing. Our research introduces a reliable crater estimation formula along with an innovative performance-based design approach, ensuring greater accuracy and improved structural resilience," said Dr. Alagappan.

Future Prospects and Applications

Moving forward, the research team aims to develop lightweight and cost-effective ballistic-resistant panels, particularly for military applications and security-sensitive areas. The proposed design framework has undergone extensive experimental validation, making it a game-changer in the field of ballistic protection for infrastructure.

By implementing these findings, critical infrastructure can be fortified against missile threats, ensuring enhanced safety and long-term durability in defense and strategic installations.
