摘要：
The effect of the presence of crack located at the fastener hole surface of bolted metallic (mild steel) and polymeric (Cross-ply [0/90](4s) glass fiber reinforced epoxy composite laminate) joints on their ultimate strength and converting their mode of failure has been studied numerically and experimentally. The present results showed that, the failure mode of bolted metallic joint is more sensitive to the presence of the crack than that of bolted composite joint. The critical crack length at which the bolted metallic joint failure mode changed from bearing failure to tensile failure has been recognized. (C) 2015 Elsevier Ltd. All rights reserved.
