The cylindrical interface crack in a layered tubular composite of finite thickness under torsion

The Yoffe-type moving tubular interface crack in a hollow composite cylinder with finite length

“…The crack is simulated as a continuously distributed dislocation, and then, the singular integral equation method is utilized to solve this problem. Numerical results of the stress intensity factors obtained in the present study are in agreement with the previous work for the static crack with the F-F edges [9] when the crack moving velocity is negligible and the…”

“…Fig. 4 shows that if v ¼ 0 the present numerical results agree well with those of Li et al [9] (see Fig. 7 of Li et al [9]).…”

“…Let us consider a center static tubular interface crack in a composite cylinder with F-F edges, which is investigated by Li et al [9]. The geometric and physical parameters of the present problem can be changed to simulate the crack problem of [9], such as v ¼ 0 and the length L is far greater than the crack length b À a.…”

“…When a cylindrical interface is debonded, the angular sizes of interface crack in the models mentioned above are supposed to be only a part of the angular range; however, the crack may even occupy the whole angular range. Recently, the problem of a tubular interface crack in a bi-layered cylindrical composite of finite thickness under torsion is investigated by Li et al [9].…”

Saint-Venant torsion of orthotropic bars with rectangular cross section weakened by cracks

“…Problem of torsion of a cylindrical interface crack in a bi-layered tubular composite of finite thickness was investigated by Li et al (2013). Two elastic cylinders were perfectly bonded to each other on the cylindrical surfaces, except for an interface cylindrical crack.…”
