| Summary: | In this paper, numerical solutions of multiple cracks problems in an infinite plate
are studied. Hypersingular integral equations (hieq) for the cracks are formulated
using the complex potential method. For all kernels such as regular or hypersingular
kernels, we are using the appropriate quadrature formulas to solve and evaluate
the unknown functions numerically . Furthermore, by using this equation the stress
intensity factor (SIF) was calculated for crack tips. For two serial cracks (horizontal)
and two dissimilar cracks (horizontal and inclined), our numerical results agree with
the previous works. |
