A single computational framework unifies crystal plasticity and fracture to reveal the stress-driven shift from ductile trans-granular to quasi-brittle inter-granular creep rupture.
UniPolicy is proposed, an objective-aware multi-policy alignment framework that supports parallel, business-customizable multi-policy beam search, flexibly allocating candidate quotas across objectives under a fixed retrieval budget and outperforming single-objective reinforcement learning and naive reward-fusion baselines.
