摘      要：Composite-metal joints with a metal insert are one kind of connecting *** this paper,tensile experimental tests were carried out to investigate tensile properties of a compositemetal joint with a novel metal insert *** element models of the joint were established,and strain distribution and tensile strength were *** numerical results are in good agreement with the experimental *** show that the joint failure is dominated by shear properties of the resin *** the resin layer thickness in a certain range will improve the tensile strength of the joint,while increasing the radius of the fillet on the ending side of the metal insert will decrease the joint *** the resin layer plasticity will improve the joint *** effect of the embedded depth of the metal insert can be ignored.
