33.2. Problem Description

The model exhibits ¼ symmetry, so one quarter of the geometry is analyzed. The idealized 2D planar model is shown below.

The quarter-symmetry model has 15 piezoelectric stacks (30 in the full model). The polarization direction is defined as the element's x axis (aligned with the global X axis), and the element coordinate system x-axes alternate between each piezoelectric ceramic.
