Quan, H. (author), Alderliesten, R.C. (author)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...journal article 2022

Quan, H. (author), Alderliesten, R.C. (author)An energy equation for fatigue crack growth was proposed. It equates the total external work per cycle (dW/dN) to the sum of plastic dissipation (dU<sub>pl</sub>/dN), change in strain energy stored (dU<sub>e</sub>/dN) and the energy dissipated in new crack surface formation (dU<sub>a</sub>/dN). Fatigue crack growth experiment of 7075-T6 was...journal article 2022

Quan, H. (author), Alderliesten, R.C. (author)Plastic dissipation accompanies fatigue crack growth in ductile materials. Previous studies presented a relation between plastic dissipation (dW/dN) and the fatigue crack growth rate (da/dN), where some researchers assumed a linear relation between both to enable crack growth predictions. To study the validity of this assumption, this paper...journal article 2021

Pascoe, J.A. (author), Zavatta, N. (author), Troiani, E. (author), Alderliesten, R.C. (author)The effect of adhesive thickness on fatigue crack growth in an epoxy film adhesive (FM94) was investigated, using a combination of experiments and numerical modelling. For the range of thicknesses investigated an increased thickness led to an increased crack growth rate. It was found that the energy required per unit of crack growth did not...journal article 2020

Usman, M. (author), Pascoe, J.A. (author), Alderliesten, R.C. (author), Benedictus, R. (author)The effect of temperature on fatigue crack growth in epoxy adhesive bonds was investigated for a range of temperatures from -55 to 80[U+202F]°C. The fatigue crack growth behaviour was characterised using both strain energy release rate (SERR) and by measurements of energy dissipation. It was found that for a given maximum SERR, or a given...journal article 2018
