Flexibility of cracked composite beams

Marek Krawczuk, Wiesław Ostachowicz
The paper presents a method of creating of the flexibility matrix of a cracked composite beam. The presented method has general character and may be used to determine the flexibility matrix for beams with other types of cracks (double-edge, elliptical, internal, etc.) if their stress intensity factors are known. The presented flexibility matrix can be applied to formation of stiffness matrix of cracked beam finite elements.
