SUMMARY:From Shock to Shield: Designing Materials for Space\, Defense\, and Beyond
DESCRIPTION:The next frontier of materials innovation lies in designing systems that not only survive but thrive under harsh environments. From hypersonic vehicles and next-generation defense systems to lunar construction and in-space manufacturing\, the demand for ultra-lightweight\, high-strength\, and resilient materials has never been greater. Yet\, our ability to understand and design materials that endure such conditions remains limited by slow\, expensive testing and computationally intensive models ultimately leading to a lack of physical understanding of mechanical response. In particular\, data describing how materials deform and fail under ultra-high strain-rate loading conditions which are typical of aerospace and defense structures—are exceptionally scarce. As a result\, materials development has relied on costly\, well-established systems; but the emergence of commercial space and reusable aerospace structures now demands a new generation of high-fidelity insights into material behavior under dynamic extremes.\n\nIn this talk\, I will introduce a new data intensive high-throughput experimental framework for probing material behavior under extreme dynamic loading. At its core is an automated laser-driven micro-plate impact platform that enables rapid\, cost-effective measurement of key material properties under shock loading. For the purpose of this talk we will in particular look at the Hugoniot Elastic Limit (the onset of plasticity under uniaxial strain loading) and spall strength (the threshold for dynamic fracture) of metals\, when subjected to ultra-high strain rate impacts (10^6 to  10^7 /s). Traditionally\, these properties required large-scale\, single-shot experiments; this new approach achieves them with statistical richness and precision\, dramatically accelerating the rate of materials discovery for extreme environments. Using this dataset\, I will discuss how loading kinetics\, microstructure\, and composition govern material performance\, and how transforming a data-scarce field into a data-rich one enables AI-driven approaches such as active learning and Bayesian optimization for autonomous extreme-mechanics experimentation.\n\nLooking ahead\, integrating this data-rich experimental capability with AI-driven modeling and automation opens a pathway toward physics-informed design principles for lightweight alloys\, ceramics\, and architected composites. In the near term\, this framework will shorten material certification cycles for hypersonics and spacecraft\, rapidly and cheaply explore a wide range of potential materials solutions; in the long term\, it will enable data-driven design of resilient materials for aerospace\, defense\, energy applications and beyond. By uniting experimental mechanics\, data science\, and materials design\, this work lays the foundation for a new era of adaptive\, high-performance materials engineered for extremes.\n\nSpeaker : Dr. Piyush Wanchoo\n\n\nBiography:\nDr. Piyush Wanchoo is a Postdoctoral Fellow at Johns Hopkins University’s Hopkins Extreme Materials Institute (HEMI). His research focuses on understanding how materials behave under extreme conditions such as shock\, impact\, and blast loading. He develops high-\nthroughput\, AI-integrated experimental platforms that enable rapid\, data-driven discovery of material solutions for aerospace\, defense\, and space applications.

SUMMARY:Ph.D. (Engg): Aerodynamic Shape Optimization of Low Observable Air Intake Duct : A Gerlach Inspiration
DESCRIPTION:Air intake system supplying air to the aircraft’s propulsion system is an important part of the aircraft. In modern military aircraft\, air intake ducts are bent due to stealth and layout considerations. Due to significant contribution from rotating jet engine components to Radar Cross Section\, need to inhibit direct line of sight of the Engine Face from RADAR’s eye is required and this leads to aggressively turning ducts. Owing to large pressure loss happening due to the secondary flows and consequent flow separation arising out of centrifugal forces or its gradients during flow turns\, total pressure recovery at Engine Face is likely to suffer. This thesis addresses this concern\, specifically for a top mounted serpentine intake duct of flying wing configuration.\n\nA shaping technique called “Gerlach Shaping” proposed by C. R. Gerlach and E. C. Shroeder to minimise secondary flows and subsequent losses forms the core of this thesis. An important feature of the shaping concept is the use of ideal flow assumptions for a flow known to be viscosity driven. As a part of the current research\, formulation and implementation of Gerlach shaping is subject to detailed analysis. Gerlach shaping principles are extended\, opening further possibilities for low loss bend designs. Radial pressure gradients and secondary flow mixing are managed more efficiently leading to smooth flow with reduced flow separation and pressure drops. Superiority of newer designs called “Gerlach Inspired Bend Designs” are proven on a square elbow and RAE M 2129 S-duct. It may be surprising to note that the losses encountered in one of the 90◦ bend designs is even lower than that of a straight duct.\n\nA new methodology called “Gerlach Inspired Duct Optimization” for aerodynamic shape optimization of low observable air intake duct design driven by conflicting aerodynamics and stealth requirements is developed. Understanding of Gerlach shaping principles gained during the evolution of design methodology for low loss bends is a stepping stone to the optimization process. Keeping the spirit of Gerlach Shaping alive\, the highlight of this process is the use of low fidelity inviscid CFD tool for a problem considered to be highly viscous. The step is crucial as integrating CFD simulations with Gerlach Shaping as against ideal flow assumptions would considerably improve the accuracy of the flow field description and enhance the duct design. Moreover\, integration of an inviscid solver facilitates robust\, fast generation of flow field and a large number of candidate designs could be analysed. A completely automated Genetic Algorithm based optimization framework integrated with Computational Fluid Dynamics simulations to realize this methodology inspired by\nGerlach Shaping gives substantial performance enhancement as compared to Reference Duct (designed using conventional design methodology) and Gerlach Duct (generated by morphing the reference duct as per Gerlach shaping).\n\nSpeaker : V Valliammai\n\nResearch Supervisor : N. Balakrishnan
