In this study, the acoustical and vibrational effects of radiating ultrasound waves to the human aorta is investigated. The aortic segment, which is composed of three distinct layers of tunica intima, tunica media and tunica adventitia, is modeled by a thick laminated composite cylindrical shell. The vibro-acoustic response of the aorta, which includes the amplitude of vibration in the longitudinal, circumferential and radial directions and the amplitude of the transmitted wave, under the acoustic excitation is obtained using the first order shear deformation theory. The maximum amount of acoustical energy that transmits through the aortic wall occurs in the range of frequencies between 10 kHz and 1 MHz. the results show two resonance phenomena in the audible range of frequencies from 100 Hz to 20 kHz with excessive vibrations of the aortic wall in the circumferential and longitudinal directions. However, the radial motion becomes dominant by increasing the frequency in the ultrasound range of frequencies from 100 kHz to 10 MHz.

在这项研究中，研究了向人主动脉辐射超声波的声学和振动效应。主动脉节段由三层不同的内膜，中膜和外膜层组成，以厚的层压复合圆柱壳为模型。使用一阶剪切变形理论，可以获得在声激发下主动脉的振动声响应，包括纵向，周向和径向的振动幅度以及透射波的幅度。穿过主动脉壁的最大声能发生在10 kHz至1 MHz之间的频率范围内。结果表明，在主频壁在周向和纵向方向上过度振动的情况下，在100 Hz至20 kHz的可听频率范围内出现了两个共振现象。但是，通过将超声范围从100 kHz增大到10 MHz，将径向运动变成主导。
