摘要
The effects of interface shape on stress wave distribution and attenuation were investigated using finite element method (FEM). The simulation results indicate that when the stress wave propagates from SiC ceramic to Al alloy, the tensile stress decreases and the attenuation coefficient of the stress wave increases with increasing central angle of the concave interface between SiC and Al. But for the convex interface, the tensile stress increases and attenuation coefficient decreases with increasing central angle. As the stress wave propagates from Al alloy to SiC ceramic, the attenuation coefficient of stress wave decreases with increasing the central angle of the concave interface. For the convex interface, the attenuation coefficient increases with increasing central angle.
