Singular integral equation method is one of the most effective numerical methods solving a plane crack problem in fracture mechanics. Depending on the choice of the density function, very often a higher order of sigularity appears in the equation, and we need to give a proper meaning of the integration. In this article we address the Hadamard finite part integral and how it is used to solve the...

Lifetime is a basic support for the thermal insulation function of barrier coatings (TBCs). Therefore, extending life span essential to develop next-generation TBCs. For this objective, columnar structure formed by vertical cracks appears make sense. However, underlying mechanism still unclear. This work scrutinizes influence periodic on cracking behavior in order tailor high strain tolerant A ...

Boundary element method (BEM) is a powerful computational tool for analysing piezoelectric problems. The BEM has been so well developed during the past 40 years that it has been considered as a very popular computational tool. This method consists of formulating the engineering problem in terms of an integral equations relating only boundary values and determining its solutions numerically. Thu...

Progressive radial cracking of a clamped plate subjected to crack-face closure is studied. The material behavior is assumed to be elastic-brittle. The cracks are assumed to be relatively long in the sense that the three-dimensional contact problem can be described via a statically equivalent two-dimensional idealization. The number of cracks is supposed large enough to permit a quasi-continuum ...

In the framework of Cost Action CERTBOND (Reliable roadmap for certification bonded primary structures), a wide group researchers from 27 European Countries have had opportunity to work on topic joints structural applications different engineering sectors such as aerospace, automotive, civil engineering, wind energy and marine sectors. Since virtual testing optimization are basic tools in proce...

This paper deals with the two-dimensional problem of elastic wave scattering from a finite crack at the interface between a coated material layer and its substrate. By adopting the Fourier transform method and introducing the crack opening displacement function, the boundary value problem is simplified for numerically solving a system of Cauchy-type singular integral equations by means of Jacob...

In the present research, a fully Automatic crack propagation as one of the most complicated issues in fracture mechanics is studied whether there is an inclusion or no inclusion in the structures. In this study The Extended Finite Element Method (XFEM) is utilized because of several drawbacks in standard finite element method in crack propagation modeling. Estimated Crack paths are obtained by ...

The goal of this paper is to evaluate the strain-based partitioning method (SBM), an analytical based on beam analysis, for mixed-mode fracture characterization asymmetric cracks. energy calculated at crack tip bending (MMB) test with geometry and material parameters. obtained using SBM benchmarked against widely applied Williams’ (WM) numerical results from finite element models virtual closur...
