Scattering of elastic waves by surface-breaking planar and nonplanar (branched) cracks has been studied in this paper. Attention has been focused on the near-field surface displacements and the crack-tip(s) stress-intensity factors. For planar normal cracks the stress-intensity factors are shown to agree with earlier results. Numerical results showing normalized vertical surface displacements are presented for incident body and surface waves. It is shown that the results for planar and branched cracks can be significantly different in some instances.
