Fig. 1. Multilayered functionally graded cantilever beam configuration with a vertical delamination crack.

In formulae (2) and (3), D u is the longitudinal displacement of the lower surface of the right-hand delamination crack arm, 1 z is the vertical centroidal axis of the cross-section of the same crack arm (Fig. 2). The displacement, D u , is related to  as

2 u h D   .
