Abstract
En 中文
• First full mapping of AM Inconel 718 initial yield surface reveals high anisotropy. • For the first time, a significant initial kinematic shift is quantified. • Cross-effect softening is identified under torsional prestrain. • Complex yield surface distortion including rotation is mapped under combined loading. • A benchmark dataset is provided for advanced anisotropic-kinematic models.
