Three-dimensional measurements of fatigue crack closure (Document No: 19840020041)
| Content Provider | NASA Technical Reports Server (NTRS) |
|---|---|
| Author | Grandt Jr., A. F. Ray, S. K. |
| Copyright Year | 1984 |
| Description | Fatigue crack growth and retardation experiments conducted in polycarbonate test specimen are described. The transparent test material allows optical interferometry measurements of the fatigue crack opening (and closing) profiles. Crack surface displacements are obtained through the specimen thickness and three dimensional aspects of fatigue crack closure are discussed. |
