Based on systemic-functional grammar,this paper gives a new definition to textual metaphor and regards it as a combination of extended metaphor and grammatical metaphor.

Optimization analysis of delamination growth in fiber reinforced metal laminates under cyclic loading;

A finite element numerical method was developed for studying the delamination growth of composite grid stiffened plates with embedded delamination in the skin.

Several important issues, including the bridging stress, the delamination growth and the prediction of the fatigue crack growth rates and the fatigue life, were addressed and summarized.
