    The influence of elastic waves on dynamic stress intensity factors (three-dimensional problems) (1996)
    Springer
    Archive of applied mechanics 66 (1996), S. 385-394 
    Details
    ISSN: 1432-0681
    Keywords: dynamic SIF ; 3D problem ; fundamental solution ; elastic waves ; rectangular and elliptic flat cracks
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Summary The fundamental solutions of the displacement discontinuity for three-dimensional problems in Laplace space are deduced in thsi paper. The displacement discontinuity method and the equivalent stress method were combined and used to determine dynamic stress intensity factors for three-dimensional time-dependent crack problems. The stress intensity factors were calcualted for dynamically loaded cracks with rectangular, circular, and elliptical crack fronts. The influence of elasticity waves (in particular surface waves) on the magnitude of the stress intensity factor and on the displacement of the crack surfaces was analysed.

    A new method for transformation of domain integrals to boundary integrals in boundary element method (1998)
    Chichester : Wiley-Blackwell
    Communications in Numerical Methods in Engineering 14 (1998), S. 1055-1065 
    Details
    ISSN: 1069-8299
    Keywords: boundary element method ; domain integrals ; dual reciprocity method ; Engineering ; Numerical Methods and Modeling

    Topics: Mathematics , Technology
    Notes: In this paper a new technique is presented for transferring the domain integrals in the boundary integral equation method into equivalent boundary integrals. The technique has certain similarities to the dual reciprocity method (DRM) in the way radial basis functions are used to approximate the body force term. However, the resulting integrals are evaluated in a much simpler way. Several examples are presented to demonstrate the validity and accuracy of the proposed paper.
