Delamination properity of 2060 aluminium lithium alloy laminate

摘要：

　　Delamination is an significant property of aluminium lithium alloy laminate for damage tolerance design.Double Crack Lap Shear specimens of 2/1 structure are used for testing delamination properity.Experiments of 2 stress ratio conditions R=0.06,0.5 are conducted,and 5 stress levels for each stress ratio.Delamination growth data b-N are obtained from 4 crack tips locations.The energy release rate,Gd,of the 2/1 structure laminate are calculated.Alderliesten modelis used for describing delamination growth db/dN and energy release rate Gd.Parameters Cd and nd in Alderliesten model are determined for R=0.06 and R=0.5 by linear fitting.An analysis is made by comparing the results of different stress ratio conditons.
