Example text

The unknown coefficient c may be calculated from the conditions on the external boundary and/or the continuity conditions on the inter-element boundary. Thus various Trefftz element models can be obtained by using different approaches to enforce these conditions. In the majority of cases a hybrid technique is used, whereby the elements are linked through an auxiliary conforming displacement frame which has the same form as in the conventional FE method. This means that, in the Trefftz FE approach, a conforming electric potential and displacement (EPD) field should be independently defined on the element boundary to enforce the field continuity between elements and also to link the coefficient c, appearing in Eq.

2) into Eq. 40) ¦ The integrating constants, which represent the rigid body motions, are ignored here[7]. Recapitulating, based on the procedure above the generalized plane strain piezoelectric problem is reduced to one of finding four complex potentials, si (i=1-4), in some region : of the material. Each potential is a function of a different generalized complex variable zk x1  Pk x2 . 3 Techniques of Fourier transformation In this section we briefly examine the application of Fourier transform techniques to cracked piezoelectric materials.
