The dynamic behaviour and crack detection of a beam with a crack
TL;DR: In this paper, an element stiffness matrix of a cantilever beam with a crack is derived from an integration of stress intensity factors, and then a finite element model of a cracked beam is established.
Journal ArticleDOI
A modal parameter identification technique and its application to large complex structures with multiple steady sinusoidal excitation
TL;DR: In this paper, a modal parameter identification technique with multiple steady sinusoidal excitation is proposed, where the force amplitudes are proportional to each other, and the phases are either coincident or opposite.
