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
