Impact analysis of a liminated composite beam by the finite element method
유한 요소법에 의한 적층 복합 보의 충격 해석
Abstract
A theoretical attempt is made to analyze the dynamic contact force and response of laminated composite beams subjected to the transverse impact of steel balls. A beam finite element model based on the modified theory for laminated composites in conjunction with static contact laws is formulated for the theoretical investigation. Finally, it is shown that the present results are in good agreement with some existing solutions or wave propagation theory.
