波在各向异性介质中传播规律的无网格法数值模拟

NUMERICAL SIMULATION OF WAVE PROPAGATION IN ANISOTROPIC MATERIAL USING MESHLESS MESHOD

  • 摘要: 采用基于紧支距离基函数近似的配点型无网格方法对波在各向异性层状介质中的传播规律进行了数值模拟,得到了应力波的传播历程,并与冲击载荷作用下的有限元计算结果值进行了比较。该方法所得到的结果与有限元计算的结果吻合较好。说明该方法可以有效地模拟波在各向异性材料中的传播过程。

     

    Abstract: An approach to the modification of the compactly supported radial basis functions (RBFs) is proposed and used to simulate the wave propagation in an anisotropic laminate. The correlative matrixes and the procedures of solution are presented in the paper. Three examples simulating wave propagation in isotropic and anisotropic plates are used in the paper to verify this method. The stress wave propagation histories in the examples are obtained. The comparison is also made between the results by this method and the results by finite element method. The good agreement shows that this method can be used to simulate the wave propagation history in anisotropic material efficiently.
