Code for: Physics-informed versus data-driven surrogates for residual stress after wire drawing

Code, run log and verification scripts behind the paper "Physics-informed versus data-driven surrogates for residual stress after wire drawing: accuracy, physical admissibility and behaviour outside the training range". Starting from the raw Abaqus reports of 2443 axisymmetric finite-element simulations of single-pass drawing of AISI 1020 steel wire, the code rebuilds the two datasets of the paper (1756 cases each), reruns the matrix of 341 training runs that compares a multilayer perceptron, a strong-form physics-informed network and a weak-form variational physics-informed network, regenerates the result tables and field figures, and reproduces the drawing-stress verification on 112 simulations. The finite-element data are deposited in a separate Zenodo record.
