Stress Analysis of Bimaterial Strip with Debondings under Tension

抄録

A bimaterial problem of strips which are bonded at their ends is solved. The bonded part is one part and debondings occur on both sides of the interface. The debonding lengths are changed, and concentrated loads are applied at the tips of each strip. The complex variable method and a rational mapping function are used for the analysis. Stress distributions are shown for two different locations of the interface. Stress intensity of debonding is defined and the values are obtained for various debonding lengths. Debonding and the effect of material constants on debonding are also investigated.
