Abstract

Abstract

En 中文
• Unified thermo-mechanical framework for temperature-driven fracture in CFRP–Al joints. • Integrated experimental–analytical R-curve method to isolate thermal toughening. • Quantifies temperature-dependent fiber-bridging tractions and fracture resistance. • Accounts for CTE mismatch thermal pre-strain controlling crack initiation and fracture modes. • Temperature-dependent CZMs with adaptive laws accurately match experiments across regimes.
Keywords:
