Proc. ASME. IMECE97, Rheology and Fluid Mechanics of Nonlinear Materials, 91-99, November 16–21, 1997
Paper No: IMECE1997-0477
...Abstract Abstract An elementary analysis of wave propagation in viscoelastic materials is presented. Data on linear viscoelasticity obtained with ultrasound high frequency wave excitation are reviewed in this light. It is concluded that such data seem to indicate that a), propagation of very...

... of attenuating wave components are included in the formulation. The wave propagation-based matrix algebra leads to recursive algorithms which are suitable for computer coding. Three examples are presented to illustrate the numerical procedure. rotating Timoshenko shaft wave propagation DE-Vol. 98...

... direction. The elastic response of a plate with the modeled sensor was computed in closed form at small time steps, and the coupled piezoceramic constitutive equations and the electrical circuit equations were solved. Sensor voltages and wave propagation responses were computed in the simulations...

... taking both mechanical motions and electrical characteristics into account should all be employed to provide a systemic overview of the piezoelectric sensors/actuators (even arrays of them) and the host structures. This use of PWAS for SHM has followed two main paths: (a). Wave propagation (b...
