1) A double trapezoidal specimen will generate shear debonding.

2) Debonding was detected for hot water immersions.

3) Interfacial debonding is one of the main damage forms of reinforced concrete materials and structures.

4) The problem of interfacial debonding fiber pullout in fiber - reinforced brittle matrix composite material is analyzed.

5) Debonding and pull - out of fibre from an elastic matrix were analysed.

6) Procedures of simulating stick, slip and bonding or debonding state of node pairs and stiffness matrix symmetrization are presented.

7) Energy release rate of interface debonding in ceramic composites is calculated by FEM.

8) There are five kinds of flaws: fibre breaking, interfacial debonding, substrate cracking, void, interface friction.

9) In composite laminates there are four basic failure modes: matrix cracking, delamination, fiber breakage and debonding.
