- Abstract
- The transient quasi-static Ritz vector method (TQSRV) is applied to efficiently calculate the transient response of a delaminated biocomposite laminate. Delamination of the laminated biocomposite structure was modeled using an improved layerwise displacement field. The piezoelectric coupling effect was modeled using higher order electric potential. One piezoelectric actuator was used to excite the laminated biocomposite plate, and one piezoelectric sensor was used to detect the transient structural response of the plate. Single discrete delamination was seeded in the laminated biocomposite plate, to investigate the effect of delamination. Three different locations of delamination through the thickness direction were considered, to study the effects of delamination on structural response. The Newmark-beta algorithm and the model order reduction (MOR) method were used, to obtain transient response of the delaminated composite plate under impulse loading. The effects of delamination were clearly observed in the power spectral density of the piezoelectric sensor output. From the results, it is concluded that the MOR is a very efficient method in predicting the damage effects of delaminated biocomposite structures.
