Discrete dislocation plasticity analysis on the plasticity-shielded cleavage in FCC crystals

Key Points

• Cleavage resistance in FCC crystals is greatly influenced by dislocation behavior, altering material durability.
• Key evidence shows that plasticity-shielded cleavage can enhance strength under specific stress distributions.
• The approach utilized a discrete dislocation plasticity framework to analyze deformation mechanics in FCC crystals.
• These findings imply that adjusting dislocation patterns can lead to stronger materials, requiring further practical tests.
