Abstract

fetched live from OpenAlex

The predictions of two viscoelastic constitutive models: one in an integral form and the other with a differential form, are compared with the experimental results presented in Part I and in Ref. 3. The experimental data include the stress-strain response ofthe epoxy resin under various loading paths with different strain combinations, and the stress envelopes of the same octahedral shear strain amplitude but with different strain rates and a cyclic ratcheting strain test. The results of this investigation indicate that while both n~nlinear viscoelastic constitutive models predict the general trend of the experimental behaviour, the quantitative comparison is not accurate enough, especially when a high hydrostatic stress component is present or under cyclic loading. It is found that the stress envelopes predicted by a modified von Mises (Stassi) criterion have a better correlation with the test results.

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.
