研究了部分脱层复合材料层合板在刚性球冲击下的动力响应。采用考虑剪切变形影响的九节点等参单元进行有限元分析。为了计算冲击器与层压板之间的接触力，采用赫兹接触定律。采用Newmark算法求解冲击器的运动。为了有效地处理两个分层层之间的动态接触问题，提出了一种结合特殊时间积分算法的拉格朗日乘子技术，克服了经典拉格朗日乘子方法的不足。数值结果对分层复合材料层合板的冲击现象提供了丰富的信息。
This paper concerns the dynamic response of partially delaminated composite laminates impacted by a rigid ball. Nine-node isoparametric elements including the influence of shear deformation were used in the finite element analysis. In order to evaluate the contact force between the impactor and the laminate, the Hertzian contact law was adopted. The Newmark algorithm was employed to solve the motion of the impactor. To deal with the dynamic contact problem between two delamlnated layers effectively, a Lagrange multiplier technique incorporated with a special time integration algorithm was presented to overcome the deficiency of the classical Lagrange multiplier method. The numerical results give much information of impact phenomena of delaminated composite laminates.
