Abstract
This paper focuses on the design and analysis of a bolted patch repair for thick composite plates. Twodimensional finite element analyses using MSC/NASTRAN were carried out for the design and analysis of a patch repair of a bi-axially loaded composite plates with a damage hole. In order to study the patch effect on the stress/strain level around the damage hole, a variety of repair patch configurations were designed and analyzed. The patches, which were made of fiber metal laminates GLARE-3, were examined for different patch thickness, fastener diameter and spacing, number of fasteners and fastener pattern. The repair efficiency was also investigated in terms of the strain reduction at the damage hole and the deficiency of the patch was examined in terms of the strain increase at fastener holes. Numerical results indicated that a balance of the stress level at the damage hole and the fastener holes must be achieved to obtain the desired patch repair performance.

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 it
