SUMMARY:Space Domain Awareness in the Artemis Era
DESCRIPTION:Since the Apollo era\, space has become an increasingly valuable domain for national security due to diplomatic\, informational\, and economic reasons. The last few years have seen exponential growth in the launch of space objects and there is an increased interest in having a permanent cislunar presence through the Artemis program. The understanding of motion of a spacecraft in multi-body environment is essential to transit between different regions in the cislunar space and to forecast and track objects in the cislunar space. The perturbed two-body restrictive framework has led to extensive modeling\, analysis\, and analytical solutions to study spacecraft motion in orbits around the Earth. However\, beyond GEO (XGEO) the dynamical environment shifts\, and the structure of fundamental behaviors can be radically different. The primary challenge that limits the transferability of tools and techniques from the GEO to XGEO region is non-Keplerian dynamics\, data sparsity from limited coverage and availability of sensors. The process of orbit determination and forecasting the path for an object based on short time arc observations is not trivial. This talk will introduce novel tools to track spacecraft motion in cislunar space and transfers between different regions in cislunar space. These tools make use of dynamical system theory in combination with advances in optimal control theory to provide a better understanding of transport mechanisms in cislunar space. Local orbit elements will be discussed to characterize the trajectories in the cislunar space.\n\nSpeaker : Dr. Puneet Singla\n\nBiography:\n\nDr. Puneet Singla is a Harry and Arlene Schell Professor of the Aerospace engineering at the Pennsylvania State University (PSU).

SUMMARY:Onboard Trajectory Optimization for System Autonomy on Saturday
DESCRIPTION:Onboard trajectory optimization lies at the heart of true system autonomy\, including UAVs\, Robots\, spacecrafts\, launch vehicles\, missiles\, and so on. Onboard trajectory optimization in real time (optimal guidance) can be generally viewed as a difficult problem. However\, it holds great promise for true system autonomy. The complex interplay between autonomy and onboard decision support systems introduces new vulnerabilities that are extremely hard to predict with most existing guidance and control tools. In this tutorial workshop\, the basic background behind trajectory optimization and computational guidance will be reviewed first. Next\, some recent advances in stabilized continuation techniques for solving two-point boundary value problems with convergence and compute guarantees will be discussed. These concepts further extend for applications to broad classes of trajectory guidance applications for aerospace flight systems including the accommodation of higher-fidelity models through bootstrapping techniques. These technical foundations will be highlighted through illustrative examples for optimal trajectory guidance inside dynamic and uncertain environments. The topics covered will also include an overview of optimal computational guidance with its relevance for challenging aerospace missions. \nLectures:\n1.Overview of Trajectory Optimization (Optimal Control)\n2.Stabilized Continuation for Onboard Trajectory Optimization\n3.Computational Guidance for Aerospace Missions\n4.Bootstrapping Techniques for Onboard Trajectory Optimization \n  \n

SUMMARY:Ph.D. (Engg): Compressive behavior of continuous fiber polymer composites in the presence of process-induced defects
DESCRIPTION:The current work examines how process-induced defects influence the compressive behavior of composite structures. The defects analyzed include wrinkles at the macroscale and fiber misalignment at the microscale. Uni-directional carbon fiber-reinforced polymer composites with intentionally created wrinkles were produced by strategically positioning laminate strips. Through comprehensive experimental characterization\, the research thoroughly investigates the impact of wrinkle characteristics and their locations on compressive strength and failure modes. Furthermore\, the study explores how these wrinkle features affect the final kink bandwidth\, angle\, and inclination. Fractographic analysis of the failed specimens identified several damage modes across different length scales\, such as kinking\, delamination\, buckle delamination\, crushing\, fiber pullout\, matrix cracking or failure\, and fiber failure. These findings highlight the importance of considering the geometry of the wrinkles and the various damage modes at different scales when creating a numerical model to accurately predict the compressive behavior of the composite.\nUtilizing the damage modes identified through experimentation\, a three-dimensional repeating unit cell framework is used to investigate how various competing damage mechanisms—such as fiber failure\, matrix plasticity and cracking\, and fiber/matrix debonding—impact the compressive behavior of the composite material. A series of parametric studies is performed to evaluate the effects of factors like fiber volume fraction\, fiber misalignment\, and interfacial properties (including strength\, fracture energies\, and friction) on compressive performance. The results reveal a strong correlation between compressive strength and kink band characteristics with fiber volume fraction\, fiber misalignment\, interfacial shear strength\, interfacial friction\, and matrix cracking. This highlights the necessity of accurately characterizing the mechanical properties and geometric features of the composite constituents.\nTo account for the impact of realistic microstructures on compressive behavior\, a two-step homogenization process has been proposed to reduce computational demands and improve the efficiency of the numerical model. In the first step\, the model captures the homogenized elastic properties and longitudinal compressive behavior. These properties are then used as inputs for a model that consists of multiple domains discretized with Voronoi polygons\, each assigned a specific initial fiber misalignment angle based on a statistical distribution. The homogenized compressive behavior has been validated against previous studies and shows strong agreement. Additionally\, the proposed method has the potential to develop into a multiscale modeling strategy that predicts compressive behavior by considering variations in realistic microstructural characteristics. \nSpeaker:  Shashidhar K \nResearch Supervisor : Prof. Kartik Venkatraman (on behalf of Prof Suhasini Gururaja)

SUMMARY:Nature of Phase Kinetics and Memory in Shape Memory Alloys
DESCRIPTION:Shape Memory phenomenon in some intermetallics like NiTi is well known. However\, during arbitrary thermomechanical loading\, these materials exhibit several other interesting\, yet less-understood phenomena. In this talk\, Thermal Arrest Memory and associated effects during interrupted phase transformations in shape memory alloys are discussed and some fascinating underpinnings in the associated martensitic transformations are highlighted.\nThe research talk will be followed by a presentation by the speaker about potential Research and Teaching initiatives and future directions toward collaborative activities at the department. This will include a brief overview of the R&D experience of the speaker over 3 decades\, and a strategy to pursue Research and Development of allied Aerospace technologies and engage with relevant organizations. A brief overview of proposed elective courses like Advanced Aerospace Materials\, and Life-Cycle Analysis and Design of Aerospace systems and components is provided. These are aimed at enhancing the academic level of the students of the department and making them more contemporary. \nSpeaker : Dr. Vidyashankar Buravalla \nBiography :  \nDr. Vidyashankar Buravalla obtained his Ph.D in Aerospace Engineering from IISc in 1998.
