A Bayesian optimal experimental design framework with Gaussian approximation of expected information gain and surrogate Fisher information enables optimized uniaxial tests that significantly improve identifiability of history-dependent constitutive parameters over random designs.
Recrystallization boundary migration in high-purity Al is modulated by the anisotropy of local internal stress states, with no observed shear-coupled motion.
