| الوصف: | The high cost and complexity of modern rocket systems provide multiple possibilities for failure, any one of which could result in lost lives and large capital losses. One failure mode involves deterioration of the layered materials near the inside of the rocket motor case. Rocket motor incorporates four layers of materials. Each layer contributes to motor performance in some significant way, but adds complexity and increases the number of potential failure locations. One area that has caused problems is near the liner-propellant interface, which can have defects originating and evolving during the manufacturing, storing, handling, or launching of the rocket. Fracture mechanics of defects near these interfaces is not well understood. Nonlinear material behavior, property gradients, large deformations, and the damage in particulate composites all affect the mechanical behavior. ; Contains viewgraphs only. |
