Advantages

Mechanism clarified

Dynamic recrystallization softening is identified as the dominant factor driving adiabatic shear localization, providing a clear target for impact-resistant design.

Softening contributions decoupled

A crystal plasticity constitutive model incorporating dynamic recrystallization evolution quantitatively separates the contributions of thermal softening and DRX softening to dynamic instability.

Applications

• Impact protection structures：Guides design of structures that delay adiabatic shear band formation, enhancing impact resistance.
• Impact-resistant materials：Avoids local shear instability by suppressing DRX softening, improving alloy impact performance.
• Aerospace impact-resistant components：Provides micro-mechanism understanding for impact failure to support reliable aerospace component design.
