摘要：
In this article, we use a macro-mesoscopic method to analyze the forced vibration behavior of the SiCf/Ti cantilever beam. The shear-lag model was applied to determine the stress-strain relationship of SiCf/Ti composites with matrix cracking, interface debonding, wear, and failure damages under tension-compression loading. We established the cyclic tension-compression constitutive model of SiCf/Ti composites by considering the evolution laws followed by three injury patterns. From a macroscopic perspective, we use the cyclic tension-compression constitutive model to obtain the stiffness reduction at different stress levels and reduce the stiffness at different stress levels. Finally, we use Ansys software to reveal the forced vibration properties of the SiCf/Ti cantilever beam under different acceleration amplitudes.
