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 pl/dN), change in strain energy stored …

Fatigue crack initiation and propagation involve plastic strains that require some work to be
done on the material. Most part of this irreversible energy is dissipated as heat and …

The elastic-plastic J-integral is adopted to correlate fatigue crack growth data of ductile
metals. An analytical link is known to exist between the J-integral and the strain energy …

Crack closure concept has been widely used to explain different issues of fatigue crack
propagation. However, some authors have questioned the relevance of crack closure and …

Background The use of the Taylor-Quinney coefficient for introducing a thermal dissipation
term into material models relies on understanding its dependencies. These are usually …

The heat energy exchanged in a unit volume of material per cycle, Q¯, has been previously
proposed and adopted by the authors as a fatigue damage indicator, because it accounts for …

A heat energy dissipation approach has been formulated to assess the crack propagation
rate of mode I fatigue cracks in AISI 304L stainless steel specimens. The proposed …

Paris-regime fatigue crack growth in polymers is simulated via a numerical procedure. The
crack growth rate is calculated based on the assumption that crack extension is controlled by …

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 …

The suitability of using a proposed condition for simulating cyclic crack propagation in a
numerical scheme is qualitatively investigated, employing the finite element method. The …
