Abstract
An analytical approach plays an important role in evaluation of fracture toughness of materials and strength of flawed components under the condition of dynamic loading. The present work is an attempt to apply BIEM, in which the derived constraint equations are functions of the Laplace transform parameter, to dynamic SIF analysis. Some remarks are obtained for the series expansions of the kernels and the relationship between time-space solutions and the discretization interval of the Laplace transform parameter. Utilizing the extrapolation method, a calculation is carried out for the dynamic SIF of a crack located on an inner surface of piping.
