The effect of microstructure and residual stress on crack propagation in engineering ceramics

Key Points

• The research aims to understand how microstructure and residual stress affect the propagation of cracks in engineering ceramics.
• Analyzed various engineering ceramics under controlled conditions.
• Evaluated the relationship between microstructure, residual stress, and crack behavior.
• Applied mechanical testing to assess crack propagation rates.
• Increased residual stress enhances crack propagation rates.
• Variations in microstructure lead to differing crack growth behavior.
• Identified critical microstructural features that mitigate crack propagation.
