Preliminary Report on the SIDER Testing of Large-Scale Sandwich Panels
Abstract
This report presents the results of Structural Integrity and Damage Evaluation Routine (SIDER) inspection demonstrations of two large-scale balsa core panels. SIDER looks at an entire structure and identifies locations where there is variability in structural stiffness. These areas either are due to the variability of the structure itself, or are manufacturing defects or in-service damage. The parts reported in this inspection were balsa sub panels cut from a full-size panel. Each sub panel was 10 feet long by 5 feet wide. The parts identified as Panel #1 and Panel #2 had weight densities of 9 and 15 pounds per cubic foot, respectively. The parts were tested at the Naval Surface Warfare Center, Carderock Division, on Wednesday April 21, 2004. Panel #1 showed minimal damage in two distinct areas of the panel. The rest of the panel appears damage free. Panel #2 had several large areas of significant damage. These areas cover virtually the entire plate.
