Barely Visible Impact Damage (BVID) in composite materials presents a stealthy yet significant risk to structural integrity, particularly challenging due to its elusive nature. The approach adopted here diverges from traditional methodologies, focusing on the novel application of Digital Image Correlation (DIC) to map surface area changes during in-situ Compression After Impact (CAI) tests. This technique allows for an in-depth analysis of planar strains along the x and y axes, shedding light on the material's behavior under stress.
A pivotal advancement lies in developing a method for precisely identifying when BVID-induced delamination recommences. By meticulously analyzing strain pattern deviations along these axes, the onset of additional damage is accurately pinpointed, significantly improving predictive capabilities for delamination due to BVID. This approach enhances the structural integrity assessment of composite materials, bolstering safety measures.
The techniques and insights gained significantly contribute to advancing maintenance strategies and structural evaluation in aerospace composites by offering refined tools for early detection of BVID-induced damage.
