    Notes: In this paper, intergranular microfracture evolution in polycrystalline brittle materialsis simulated using a cohesive grain boundary integral formulation. A linear cohesive law is used formodelling multiple microcracking initiation and propagation under mixed mode failure conditions,encountering the stochastic e=ects of the grain location, morphology and orientation. Furthermore,in cases where crack surfaces come into contact, slide or separate, fully frictional contact analysis isperformed

    Crack Growth analysis of plates Loaded by bending and tension using dual boundary element method (2000)
    Springer
    International journal of fracture 105 (2000), S. 27-47

    Notes: Abstract This paper presents an extension of the dual boundary element method to analysis of crack growth in plates loaded in combine bending and tension. Five stress intensity factors, two for membrane behaviour and three for shear deformable plate bending are computed using the J-Integral technique. Crack growth processes are simulated with an incremental crack extension analysis based on the maximum principal stress criterion. The method is considered effective since no remeshing is required and the crack extension is modelled by adding new boundary elements to the previous crack boundaries. Several incremental crack growth analysis for different configurations and loadings are presented.

    Stiffened cracked plates analysis by dual boundary element method (2000)
    Springer
    International journal of fracture 106 (2000), S. 245-258

    ISSN: 1573-2673
    Keywords: Fracture mechanics ; dual boundary element method ; stiffened plates ; cracks ; elasticity beam.
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract In this paper a boundary element formulation for analysis of shear deformable stiffened cracked plates is presented. By coupling boundary element formulation of shear deformable plate and two dimensional plane stress elasticity, dual boundary integral equations are presented. The interaction forces between stiffeners and the plate are treated as line distributed body forces along the attachment. Both concentric and eccentric stiffeners have been considered. Rectangular stiffened plate containing a single crack and double cracks subjected to uniform distributed moment on the crack surface and uniform shear load on the plate are analysed by the proposed method. Good agreement has been achieved compared with analytical solutions.

    Dual boundary element method for three-dimensional thermoelastic crack problems (1998)
    Springer
    International journal of fracture 94 (1998), S. 89-101

    ISSN: 1573-2673

    Notes: Abstract This paper describes the formulation and numerical implementation of the three-dimensional dual boundary element method (DBEM) for the thermoelastic analysis of mixed-mode crack problems in linear elastic fracture mechanics. The DBEM incorporates two pairs of independent boundary integral equations; namely the temperature and displacement, and the flux and traction equations. In this technique, one pair is applied on one of the crack faces and the other pair on the opposite one. On non-crack boundaries, the temperature and displacement equations are applied.

    BEM Implementation of the Energy Domain Integral for the Elastoplastic Analysis of 3D Fracture Problems (1999)

    Notes: Abstract An Elastoplastic Dual Boundary Element Method (EPDBEM) for the evaluation of the J-integral in three-dimensional fracture problems is presented in this paper. The point-wise J-integral is evaluated along crack fronts using the Energy Domain Integral (EDI) methodology. The domain expression of the EDI is naturally compatible with the EPDBEM, allowing to embed the computation of the J-integral within the boundary element formulation in such a way that it only accounts for a small additional computational effort. The accuracy of the proposed formulation is demonstrated by solving problems with straight and curved crack fronts.
