Curatorial Protocols for Capturing Single-Lap Joint Test Results Using the Materials Selection Analysis Tool Platform.

摘要

Candidate adhesives for Army applications can include nontraditional chemistries, which have largely unknown mechanical and durability properties as rigorously required for engineering design criteria. It is anticipated that a potential Army-motivated adhesive requirements standard would result in a candidate qualification pool of significantly greater numbers than well-establisehd aviation counterparts. The Materials Selection and Analysis Tool (MSAT) database platform is currently being developed by the U.S. Army Research Laboratory (ARL) with guidance from NASA for capturing testing results. It is critical to document the adhesive response information without any prejudice, as models are currently not sufficiently well developed to describe the range of adhesive behaviors encountered for Army conditions. Therefore, our goal is to capture the entire experimental response curve, supportive pedigree information, and experimental descriptors, which will augment further data analysis. Increased research efficiency and improved data consistency are two significant drivers for automating mechanical testing/reporting protocols. The workflow scheme used here transfers and converts relevant load versus displacement raw data directly to MSAT as a verifiable digital asset. A separate analysis protocol is used to further reduce the data into defined and searchable metrics. Discovery protocols for culling the multifaceted data housed within MSAT to provide correlations between quasi-static adhesive performance and empirically observed response at high loading rates will eventually be developed.
