Effect of Damage on Nonlinear Dynamic Properties of Viscoelastic Rectangular Plates

  • 摘要: 研究了考虑损伤效应的粘弹性矩形板在横向周期载荷作用下的非线性动力学问题.基于Von Karman方程、Boltzmann叠加原理和连续损伤力学理论,建立了以中面位移表示的考虑损伤效应的粘弹性薄板的非线性动力学方程,然后,应用有限差分法和Newmark法进行求解,并与相应的文献作出了比较.具体讨论了外载荷参数和板的几何尺寸对含损伤效应的粘弹性板非线性动力响应的影响.数值结果表明,考虑损伤效应时,结构的非线性动力响应会发生显著的变化.
