Abstract Details

1999, Master of Science, Ohio State University, Welding Engineering.
An efficient algorithm has been proposed for simulation of ultrasonic waves with multilayered composites. The method is based on combining of global matrix method with accounting for the system periodicity. The results show this method is stable and efficient especially for cross-ply composites. Using this algorithm, the behavior of wave transmission through a laminate immersed in water have been discussed and explained by Floquet wave pass and stop bands. Based on Floquet wave representation, a homogenization procedure has been proposed to model the multilayered composite as an anisotropic homogeneous medium. To describe experimental conditions for an impulse regime interrogation of composites a beam model has been developed. Also the time- domain response in an acoustic microscopy has been investigated and a procedure to measure the elastic constant using the acoustic microscopy signature has been discussed.
