Half-layers with interface cracks under anti-plane impact

Dynamic response of cracked non‐homogeneous magneto‐electro‐elastic layer sandwiched by two dissimilar orthotropic layers

“…The distributed dislocation technique was used for the analysis of cracked bodies. [15][16][17][18][19][20] We use the solution of magneto-electro-elastic dislocation accomplished in the preceding section to analyze layered composite medium weakened by N interacting cracks. The geometry of a linear crack may be described in parametric form, as…”

“…Furthermore, the distributed dislocation technique has been proved to be a useful method in the transient analysis of medium with multiple cracks under impact loads. [15][16][17][18][19][20] The transient fracture problem of piezoelectric-piezomagnetic sandwich structures under the combined anti-plane mechanical and in-plane electrical impacts was investigated by Zhao et al 21 Transient analysis of two bonded functionally graded magneto-electro-elastic layers with multiple interfacial cracks was analyzed by Milan and Ayatollahi. 22 The transient response of multiple impermeable cracks in a piezoelectric layer bonded to an orthotropic layer under anti-plane mechanical and in-plane electrical impact loads was obtained by Ayatollahi et al 23 According to our knowledge, although crack problems in MEEM or FGMEE layer have been investigated by many researchers, the transient analysis of multiple embedded cracks in the FGMEE layer bonded between two orthotropic layers under impact loads has not been investigated.…”

Anti-plane analysis of a crack terminating at interface of the isotropic half-planes bonded to intact orthotropic layers

“…The presence of defects at the interface results in a more challenging problem. While the behavior of cracks situated along the interface of dissimilar materials has been the subject of several investigations, see, for example, Zhang, 1 Zhang, 2 and Yousefi et al, 3 the anti-plane analysis of slant cracks with a tip located at the interface of dissimilar regions is not that well undertaken, yet. Some articles dealing with finite cracks terminating at the interface of two perfectly bonded dissimilar regions undergoing anti-plane deformation are cited, here.…”
