Interaction of multiple straight cracks and elliptical inclusions in a finite plate due to mismatched thermal expansion
2020, Engineering Fracture MechanicsCitation Excerpt :However, Jin [13] presented a closed-form for exterior Eshelby’s tensor to solve the exterior elastic fields and this can make it more convenient to solve the multiple inclusion problems. Additionally, the distributed dislocation method has been widely used to solve various kinds of crack problems in infinite plates, finite plates and half plates [16–25]. Previous research [19] shows this method has considerable computational efficiency for solving a problem with large numbers of cracks and a problem of 100 cracks are solved with high efficiency.
Automated numerical simulation of the propagation of multiple cracks in a finite plane using the distributed dislocation method
2019, Comptes Rendus - MecaniqueCitation Excerpt :So, in this part, we will firstly introduce the stress caused by an edge dislocation. Based on previous research [10,15,19], we will deduce the governing integral equations for a finite plane containing multiple straight cracks and kinked cracks. Now, Eqs. (12) and (13) exactly provide the integral equations for the solution to the problem of a finite plane containing multiple straight and kinked cracks when tractions are applied on the boundary.

2018, Engineering Fracture MechanicsCitation Excerpt :It was introduced detailedly by Hills et al. [36]. DDT was applied to solve various crack problems by the previous works [37–41]. What is more, DDT can be applied to model crack tip plasticity.
Numerical studies of an array of equidistant semi-permeable inclined cracks in 2-D piezoelectric strip using distributed dislocation method
2016, International Journal of Solids and StructuresCitation Excerpt :Zhang et al. (2013) extended the concept of DDM to study the interaction between the cracks and circular inclusion present in a finite plate. Zhang et al. (2014) compared the DDM solution for multiple cracks in a finite plate of an isotropic material with the FEM. Most of the periodic cracks problems have been solved for collinear cracks present in an infinite domain.
