A high-order discontinuous Galerkin finite element method, on triangular elements, is used to model piezoelectric systems. Non-destructive testing problems are Studied. In particular, flex circuit transducer designs which can be used to obtain information about the surroundings. The focus is to look at simple transducer designs, where the system reduces to a two-dimensional plane strain problem or a one-dimensional longitudinal strain problem. Numerical modulations are compared to analytical/exact solutions obtained from a longitudinal strain model, in both time and frequency domains. (C) 2008 Elsevier Ltd. All rights reserved.
