Abstract

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.
