Analysis on the Composite Laminated Plate Subjected to Low Velocity Impact

저속 충격을 받는 복합재료 적층판의 손상해석

Recently, composite material which has much excellent mechanical characteristics has been applied in many industries. However, it has a brittle characteristic under impact event. Especially, its invisible characteristics of the damaged area has been the motivation of many engineers investigation, and the nonlinearity of the impact mechanism is one of the main reason to assume the damaged area too simple. The damage mechanism of the composite laminated plate subjected to low velocity impact using ABAQUS/Standard & user subroutine was presented here.
