EXPERIMENTAL METHODS IN SHIP STRUCTURAL EVALUATION
Experimentation has always been at the core of technological development. Even now, experiemntal evaluations are needed to validate ship structural design and performance and to lay the foundation for developing and verifying more reliable methods of structural performance prediction. Among the more recent advances in experimental methods are the development of models fabrictaed of plastics to determine stress distributions and deflections under simulated service loadings, and the application of holography for obtaining response characteristics for complex structural subsystems such as propeller blades. The use of developmental testcraft has improved the technical and economic freasibility of ship structural calibration. The measurement of responses to applied loadings thus allows model and analytical methods to be more readily validated, and the vehicle itself may be employed as a more accurate load sensor. In order to develop fatigue resistant structural details, new methods are being employed to experimentally evaluate large scale structural assemblies under cyclic loading. Improved hardware and techniques are being devised to collect and to reduce experimental data more efficiently and reliably.
