The Coulomb friction model and sticking-sliding friction model were built up respectively on the tool-chip interface.

Rotation curvature analysis of SRC member with regard to the bond slip relationship;

according to the experimental results about bond slip FRP bars and concrete around the world,the studying and present status of bond slip mechanism are introduced.

The whole bond slip curve and bond stress d.

Thusly, a new embedded combined element is developed, which can not only simulate the bond and slip between reinforcement and concrete, then get a re.

Based on the equilibrium of static forces and coordination of deformations,with considering the effects of bond strength variation and crack width development at different stress stage of reinforcement in tension cracks,the average stress strain relationship of unanchored zone of RC structure under bond and slip action has been derived.

Research on the bond-slip behavior and numerica simulation of steel reinforced concrete columns;

Summarized review of the bond-slip problems of concrete filled steel tubes(CFST);

An experimental study on the bond-slip behavior of corroded steel bars in concrete under dynamic loads;

Experimental data analysis and modeling study of bond-slip relationship between the bolt and cement-mortar

The test methods include pull-out test,bending test and the test that focuses on the local bond-slip relationships.

To gain a better understanding to the debonding failure, the intermediate shear stress was primarily evaluated by incorporating typical bond-slip (δ -τ ) constitutive models and the test results obtained by the authors and other researchers.
