Dual phase-field modeling of coupled delamination—Fracture and critical current degradation in REBCO coated conductors under combined mechanical loading
Rare-earth barium copper oxide (REBCO) coated conductors serve as second-generation high-temperature superconductors for high-field magnets and power transmission. Their multi-layer thin-film architecture accumulates stress at interfaces and within layers under mechanical loading. Delamination and fracture then cut the...
