초록
The purpose of this study was to provide fundamental data for an anchor collision simulation of an FCM (flexible concretemattress). Numerical material models (elastic-perfectly plastic model, Drucker–Prager model, and RHT concrete model) were compared. ANSYSExplicit Dynamics was used for collision analyses. An FE model was used for the anchor, FCM, andreinforcement bars. The results showed thatthe behavior of the FCM was verydifferent that those ofthe material models. In particular, the effect of the pressure dependent strength was mostnoticeable among the properties of concrete.
