Multiple Scattering Effect of Cracks

, 1999
Effect of multiple scattering is studied for cracks in the three-dimensional elastic body. The multiple scattering problem for cracks is formulated by the boundary integral equations. The Born series algorithm is introduced to solve the boundary integral equations.

Interacting multiple cracks with complicated crack surface conditions

International Journal of Fracture, 1996
In solving multiple cracks problems for the strong crack interactions, crack surfaces that are not always open even under remote tension loading, some crack surfaces may contact or even partially contact.

Multiple-cracked fatigue crack growth by BEM

Computational Mechanics, 1995
The dual boundary element method is applied to the two-dimensional linear elastic analysis of fatigue problem of multiple-cracked body. For each crack, the traction integral equation is applied on one surface of the crack, while the usual displacement integral equation is used simultaneously on the other. General multiple crack growth problem is solved

INTERACTION EFFECTS OF MULTIPLE CRACKS

17th Structures, Structural Dynamics, and Materials Conference, 1976
As a result of the physical and thermal tests on compressed cone to flat metallic contacts it is possible to predict the thermal conductance of this type of joint with confidence. Parameters required for these predictions include the shape of the deformed joint whilst loaded, and the true support pressure. The latter varies with the initial cone angle,

Scattering by Multiple Crack Configurations

Journal of Applied Mechanics, 1988
A system of boundary integral equations is presented which governs the crack-opening displacements for two-crack configurations. The integral equations are highly singular and they cannot be solved directly by numerical methods. By the approach of this paper the higher order singularities are, however, reduced to integrable singularities, and the ...

On the linkup of multiple cracks

Engineering Fracture Mechanics, 1995
Abstract The coalescence or linkup of multiple cracks is considered in this paper. Moreover, two criteria for multiple crack linkup are proposed which are based on linear elastic models. Analytical predictions of multiple crack linkup are compared with experimental results from flat panel tests. The effect of stable tearing has been included in these

Multiple crack weight for solution of multiple interacting cracks by meshless numerical methods

International Journal for Numerical Methods in Engineering, 2006
AbstractWe devise a multiple crack weight (MCW) method for the accurate and effective solution of strongly interacting cracks by meshless numerical methods. The MCW method constructs weight functions around cracks so that they simultaneously characterize all the cracks present in the single nodal domain of influence. This approach reduces the number of

Interaction of multiple cracks and formation of echelon crack arrays

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
AbstractFracturing of rock under compression is a product of a series of processes, including nucleation, growth, interaction and coalescence of multiple microcracks. The formation of echelon arrays of microcracks and macrocracks is one of the crucial rings in the processes.
