摘要: Variation of model size as determined by grid density is studied for both refinement and damage detection. In 3 it found that a large with fine preferable in order to achieve reasonable correlation between the experimental response finite element model. A smaller falls victim inaccuracies method. As become increasing finer, FE method approaches an accurate representation. detection only starting point. The refined matrix which doesn`t retain approximation, therefore captures most dynamics structure can be used preferable.
