Abstract: The coalescence conditions of plastic zones are calculated for multiple cracks in a riveted stiffened sheet using a strip yield model. The multiple cracks and their plastic zones are treated ...

Abstract: The problem of two cracks in a semi-infinite sheet is analyzed. The critical conditions when adjacent plastic zones just coalesced are obtained. Also, the conditions when a plastic zone just ...

Abstract: Crack arresting capability is experimentally examined using center cracked tension specimens and varying the placement of the dimple ahead of the crack tip. It is confirmed that the dimple gives ...

Abstract: The coalescence conditions of plastic zones are calculated for an edge crack and an internal crack in a semi-infinite sheet. The cracks and their plastic zones are treated as a fictitious ...
