Abstract

fetched live from OpenAlex

In this article, we perform a parametric study of the springback phenomenon.The effect of material parameters related to the work hardening and the thickness is studied by using computer experiments and statistical methods.First, a sensitivity analysis is performed using a fractional factorial design and a linear regression model.After determining the important factors, a Taguchi analysis is performed to estimate the optimum value of the parameters for robustness against springback.Next, we create a Gaussian process meta-model trained with the data generated via Latin hypercube sampling.This meta-model is used to better understand the nonlinearity of the response and the effect of parameter interactions.Finally, by using a Monte Carlo simulation on the meta-model we determine how the variability of the input parameters propagate to the response (springback).The pipeline explained in this work can help with establishing an effective strategy for the springback compensation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
