Dynamic Analysis of Cracked Timoshenko Beams Using the Transfer Matrix Method Kim, Jung Ho; Kwak, Jong Hoon; Lee, Jung Woo; Lee, Jung Youn;
This paper presents a numerical method that can evaluate the effect of crack for the in-plane bending vibration of Timoshenko beam. The method is a transfer matrix method that the element transfer matrix is deduced from the element dynamic stiffness matrix. An edge crack is expressed as a rotational spring, and then is formulated as an independent transfer matrix. To demonstrate the accuracy of this theory, the results computed from the present are compared with those obtained from the commercial finite element analysis program. Based on these comparison results, a parametric study is performed to analyze the effects for the size and locations of crack.
