Abstract

Abstract

En 中文
• A mechanical-environmental coupled phase-field model for 7B05 alloy fracture. • Simulating fatigue cracking without presuming crack paths. • Low temperature, stress ratio, and hydrogen synergistically degrade fatigue life. • A tool for assessing aluminum alloy durability in complex environments.
Keywords:
