【摘要】 在ANSYS软件中应用黏弹性边界单元,用Combin14单元完成了黏弹性边界的施加。算例表明其可以很好地吸收边界反射波,且当切向刚度参数不变,法向刚度参数变化时,吸收效果不受影响,反之亦然,验证了其有效性和稳定性。更多还原

【Abstract】 We present a method to realize viscoelastic boundary condition in ANSYS finite element software by using the Combin 14 element.The numerical results show that the method can well absorb the boundary reflection wave,and is insensitive to change of boundary normal stiffness parameters while the tangential stiffness parameters keep constant,and vice versa.The results also verify the effectiveness and stability of the method.更多还原
