Center for Innovations in Structural Integrity Assurance (CISIA)

About CISIA

LSU and Louisiana Tech propose CISIA as the newest center under the National Science Foundation’s Industry-University Cooperative Research Center (IUCRC) Program, which offers a proven framework to help transition industry-driven research into commercial applications. CISIA will help companies monitor, forecast, and predict structural and mechanical failure in components and structures, both existing and produced via advanced manufacturing techniques.

Our Vision

CISIA will be 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.

Our Mission

CISIA’s pre-competitive research will address structural integrity problems in deteriorating civil infrastructures and aging mechanical components, as well as new structures and components produced via advanced manufacturing techniques. By integrating validated diagnostics, machine learning and data-driven decision making, multiscale materials testing/characterization, manufacturing process characterization and parameter optimization, and multiscale physics-based modeling/simulation, CISIA will be well-positioned to elucidate and translate the links between new materials, manufacturing processes, and their collective impact on reliability across all U.S. industrial sectors.

What Does CISIA Do for Industry?

CISIA helps infrastructure, oil and gas, aerospace, marine and maritime, construction, advanced manufacturing, chemical, petrochemical, and energy processing industries and their providers lessen the financial and human impacts of mechanical and structural failure through advanced technology development in monitoring, prediction, characterization, and testing.

CISIA develops boundary-pushing and use-inspired methods, integrated industrial solutions, and support to help companies with assets in challenging environments mitigate risk and improve safety and reliability.
