Tóm tắt báo cáo

The receptance function is very important which interrelates the harmonic excitation and the response of a structure in the frequency domain. This paper presents the receptance curvature as the second derivative of the receptance. The influence of the crack on the receptance curvature is investigated. The results show that when there are cracks the receptance curvature is influenced significantly at crack positions. This might be useful for the detection of cracks. In this paper, the numerical simulation of the receptance of beam with some general boundary conditions is presented.
