N2 - An energy equation for fatigue crack growth in adhesive joints is proposed. Fatigue experiment on DCB adhesive joint specimens was used to derive the relation between fatigue crack growth rate (da/dN) and energy variables in this equation. The result shows plastic dissipation and change in stored strain energy, whose relation with da/dN both depending on the stress ratio, are not straightforwardly related to da/dN. The energy dissipated in new crack surface formation is the variable that straightforwardly related to da/dN within the range of test, and its relation with da/dN is one-to-one, regardless of the influence of stress ratio.
