MCMN Deep Learning Model for Precise Microcrack Detection in Various Materials
Bibliographic record
Abstract
Damage in metals, composites, and cemented porous solids, in the form of cracks, inclusions, and voids, is a nontrivial problem. Many experimental, numerical, and analytical methods have been proposed in the past, with some recent models deploying neural networks. However, past methods often lack the accuracy and precision needed to identify microcracks. This paper presents the MicroCracksMetaNet50E (MCMN) deep learning model, inspired by Meta's Segment Anything Model (SAM). MCMN is trained with numerical data produced by an advanced mesoscale numerical model for spatial crack detection inside various materials. MicroCracksMetaNet50E achieves an accuracy of 0.867% and a precision of 0.906% in identifying microcracks. The robust performance of MCMN is highlighted, showcasing a notable advancement that its capabilities and propels the field into uncharted territories by expanding oppor-tunities for the comprehensive exploration of additional datasets. The method could be adopted for damage detection in metals and composites in manufacturing as well as structural health monitoring.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
