Abstract
The effect of interfacial angles on stress wave propagation and attenuation in SiC/Al layered composite materials was studied by applying the finite element method (FEM). The simulation results show that the attenuation coefficient of stress wave in SiC/Al composite decreases with an increase in taper angles of the contact surface as the stress wave propagates from SiC ceramic to Al alloy, indicating that the attenuation coefficient of stress wave has a negative relationship with taper angles. However, the attenuation coefficient of stress wave increases with taper angles increasing when the stress wave propagates from Al alloy to SiC ceramic. In addition, no obvious change is observered for the attenuation coefficient of stress wave as the taper angle exceeds 210°.
