Low-Velocity Impact Behavior of Aluminum-Fiber/Epoxy Laminates: A Comprehensive Experimental Study
Bibliographic record
Abstract
Considering many potential applications of fiber reinforced metal laminates (FMLs) in sensitive structures, it is necessary to understand their mechanical behavior under impact loads. In this study, low velocity impact tests based on ASTM D7136 have been conducted on FMLs made of 1050 aluminum sheets and various types of fiber reinforced polymer (FRP) layers; namely E-Glass, Kevlar 49, and carbon T300 plain woven in the epoxy resin. Projectile energy, fiber type and the number of successive impacts are selected among important parameters that can affect the performance of FMLs. In particular, the effects of these parameters on the absorbed energy, contact force, front and rear face damage areas, central deflection and permanent deformation of FMLs have been investigated. For determining the damage area and central deflection of the specimens, an image processing method is adapted.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
