| Popis: | A crack in structural member introduces local flexibility which is function of crack depth and location. This flexibility changes the dynamic behavior of the system and its stability characteristics. A continuous cracked beam vibration theory is implemented for the lateral vibration of cracked Euler–Bernoulli beams with single-edge open cracks. In this work, the crack identification as on line health monitoring for simply supported graphite/epoxy fiber reinforced composite beams is considered. The effects of crack depth and location, fiber orientation, and fiber volume fraction on the flexibility and consequently on natural frequency and mode shapes for cracked fiber reinforced composite beams are investigated.Copyright © 2010 by ASME |
