Abstract

fetched live from OpenAlex

Abstract Under dynamic loading conditions, damage in a plain weave carbon fiber reinforced polymer (CFRP) composite is a complex and multiscale process, especially in the presence of a manufacturing flaw. In this context, this paper investigates the impact of an inserted flaw on the damage scenario and stiffness degradation over fatigue life. To achieve this objective, a full three-dimensional finite element model (FEM) is developed to evaluate the stress distribution induced by the local defect. Fatigue tests are then performed on two configurations with and without inserted flaws with continuous monitoring by using non-destructive testing (NDT) techniques. The acoustic emission (AE) method is used for damage quantification and source localization while digital image correlation (DIC) and air-coupled ultrasonics (ACU) are applied to evaluate the stiffness degradation. The cross results obtained using these three monitoring techniques provide an insight into the damage process and stiffness degradation in woven composite with a simulated manufacturing flaw.

Teacher imitation

Not 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.
