文摘

Transfer matrix method can compute exact eigenpairs of a twisted beam with cracking. The method can produce an infinite number of eigenvalues using only two sub-elements. Effects of twisting on a cracked beam are examined for some twist angles. Effects of cracking for the in-plane and out-of-plane bending vibrations are both considered. Effects of cracking on twisted beams are analyzed through a parametric study of the size and location of cracking.
