Abstract: The geometric nonlinearities in elastic sway frames are examined. Various approximate methods of second‐order analysis for sway frames are reviewed and the conditions limiting the use of these procedures are stated. A ...

Abstract: The geometric nonlinearities in elastic nonsway frames are examined and used to review the rationale and accuracy of the ACI slender column design method. The use of nonsway effective length factors to account for effects ...

Abstract: A prognostics and health management (PHM) technique has been developed and applied to a variety of safety-critical aerospace systems. The PHM performance relies highly on test data, which conveys relevant system health ...

Abstract: This work presents a novel lensed plastic optical fiber (POF), efficiently coupled with a light source. A convexo-concave plastic lens (CCPL) was bound to a flat-end plastic optical fiber using ...

Abstract: This study aims at the comparative analysis and improvement of different analytical crack models for rotating blade. Part II of this study focuses on the comparative analysis of dynamic characteristics based on modified ...

Abstract: This study aims at the systematical improvement and comparative analysis of analytical crack models for the rotating blade. Part I of this study focuses on analytical modeling, model modification, and model validation of ...
