Crack Propagation
Crack propagation is the process by which a crack or fracture in a material grows over time under the influence of stress. In the context of space and astronautical engineering, crack propagation is a critical issue as it can lead to catastrophic failure of spacecraft and launch vehicles. The harsh environment of space, including extreme temperatures, radiation, and vacuum, can accelerate crack growth and make it difficult to detect and repair. Therefore, understanding and predicting crack propagation is essential for ensuring the safety and reliability of space systems. This involves developing advanced materials and structures that can withstand the space environment and designing inspection and maintenance procedures to detect and repair cracks before they become critical.
