Advanced Materials and Designs for Aerospace and Terrestrial Structures Under Extreme Environments
Co-Chairs: An Chen, Ph.D., Iowa State University, Ames, IA and Hongyu (Nick) Zhou, Ph.D., University of Alabama-Huntsville, Huntsville, AL
New techniques in experimental, computational, and analytical mechanics are expanding the understanding of the behavior of composite, smart, and other materials with applications to aerospace structures and other terrestrial structures under extreme environmental conditions. Exciting combinations of fundamental studies and practical applications by government and industry are expanding the design and analysis capabilities for aerospace structures as well as terrestrial structures to be used in extreme environments. Recent advances and studies on materials and structures as well as their design aspects in terrestrial aviation and space applications and related structures are particularly solicited.
Special Session Topics
Ballistic Impact and Crashworthiness of Aerospace Structures
Session Organizer: Justin Littell, Ph.D., NASA Langley Research Center, Hampton, VA
The special session is focused on high strain rate testing and simulations involving structural impacts at velocities ranging from vehicle crash events to ballistic impact. Associated impact simulations utilizing state-of-the-art nonlinear explicit transient dynamic finite element codes are desired. Impacts involving aerospace structures that are constructed of unique materials such as composites, are encouraged. Finally, the topic of vehicle crashworthiness encompasses a variety of subtopics such as human tolerance to impact, modeling of crash test dummies, seats and restraints, airbag technology, and modeling of impact surfaces including soil and water.
Energy Efficient Structures and Habitats
Session Organizer: Jialai Wang, Ph.D., The University of Alabama, Tuscaloosa, AL
The special session is focused on energy-efficient structures and habitats that are suitable for earth and space applications. The topic encompasses a range of topics including the use of emerging materials and technologies such as Phase Change Materials (PCM), high-insulation structural composites, hydronic heating and cooling, combined structural and thermal analysis and simulations, and the structural responses under elevated (or cryogenic) temperatures. In addition, submissions pertaining to the scale-up applications of additive manufacturing (e.g., 3-D printing concrete and shelters) and fast-deployable structures are encouraged.
Advanced and Alternative Cementitious Materials
Session Organizer: Chris Ferraro, Ph.D., University of Florida, Gainesville, FL
The use of new advanced and alternative building materials for the creation and maintenance of structures is beneficial to industry and the environment. This special session includes topics related to new and advanced concepts pertaining to green, resilient, and high-performance materials. The session includes the contributions to the behavior of alternative materials including mechanics, fatigue, fracture, durability, and resilience. Additionally, submissions that address issues in additive manufacturing, and materials applicable for terrestrial and extraterrestrial structures, are encouraged.
Composite Materials for Aerospace
Session Organizer: Gregory Odegard, Michigan Technological University, Houghton, MI
Composite materials are increasingly used in aeronautical and aerospace applications because of their high specific strength and specific stiffness, as well as their insulative capabilities. However, much research still needs to be performed to improve the efficiency of processing composite structures, as well as improving the properties without sacrificing their low density. This session will focus on efforts to improve properties and processability of composites, including experimental and computational modeling approaches.
