![]() Louisiana State University (LSU) and Louisiana Tech University (LA Tech) have established the Industry-University Cooperative Research Center (IUCRC) for Innovations in Structural Integrity Assurance (CISIA). Validated diagnostics for structural evaluation.Nondestructive structural integrity analysis methods and algorithms.New structural materials and fabrication methods.Machine learning to better predict asset conditions. ![]() Innovative testing methodologies for newly developed structural repair materials.Fully structural repair materials for buried pipeline assets.Design of dynamic high-stress interfaces.Continuous structural health monitoring.With state-of-the-art research facilities, CISIA specializes on research involving: CISIA leverages its extensive infrastructure for research into installation, inspection, structural health assessment, and rehabilitation of underground utility systems as well as innovative nondestructive evaluation methods for above-ground civil infrastructure.īy integrating validated diagnostics, machine learning, and data-driven decision-making, CISIA will elucidate and translate the links between new materials, manufacturing processes, and service histories, and their collective impact on reliability across all U.S. industries.ĬISIA focuses on structural integrity and materials innovation - with emphasis on multiscale materials characterization and testing, and multiscale physics-based modeling and simulation - to research component and civil asset fatigue, wear, lifetime assessment methods, and nondestructive accelerated testing. These engineers will join a highly qualified and productive workforce that significantly enhances the global competitiveness and resilience of U.S. The academic and industrial members of CISIA work in concert to produce a diverse workforce of engineers who are trained in state-of-the-art facilities to utilize modern methods of structural health monitoring and analysis. Establishing linkages between material properties, infrastructure performance, and structural integrity requires multi-disciplinary research collaborations CISIA is well-positioned to elucidate and translate these links and their collective impact on reliability across all U.S. CISIA conducts use-driven, fundamental, pre-competitive research to establish linkages between material properties and infrastructure performance in terms of its structural integrity. CISIA serves as a trusted source of transformative insights, predictive capabilities, and materials innovations across broad industrial sectors, focusing on structural integrity assurance for small and large structures and mechanical components. Disposition Table for Public Comments AC 91-56B.Structural integrity and reliable life prediction of infrastructure and mechanical components have relevance in every public and private sector, ranging from energy to aerospace to construction to chemical processing industries. ![]() The procedures set forth by this AC are applicable to the large transport category airplanes operated under Subpart D of part 91, and parts 121 and 125. Guidance material on this subject for other transports is provided in AC 91-60. ![]() This guidance material applies to large transport airplanes which were certified under the fail-safe and fatigue requirements of Civil Air Regulations (CAR) 4b o 14 CFR part 25 of the Federal Aviation Regulations (FAR), prior to Amendment 25-45, and which have a maximum gross weight greater than 75,000 pounds. Provides guidance material to manufacturers and operators of transport category airplanes for use in developing a continuing structural integrity program to ensure safe operation of older airplanes throughout their operational lives.
