✦ Synopsis
Plates with centraI through cracks subjected to bending is analysed taking into account the closure of ihe crack faces on the compression side. A r~ee-dimension finite element method emplo~g t~ee~~ensjon~ degenerate SOB element is used for the amdysis. The crack faces have been mode&d such that they come in contact over an area on the compression side and interfere with each other. The infhrence of the crack closure on the variation of the stress intensity factor across the plate thickness is obtained for finite and infInite plate geometries.
