Applied Mathematics Seminars: Fatigue, Damage and Fracture by a Ginzburg-Landau Phase Field Model

Presented by Mauro Fabrizio, University of Bologna

3 March 2017 14:00 in CM219

The notion of fatigue is founded on the concept of degraded or tired material and is linked to the observation of damage, a consequence of the loading and unloading cycles. It is apparent that fatigue produces progressive damage involving plastic deformation, crack nucleation, creep rupture and finally rapid fracture. So, damage is the consequence of the gradual process of mechanical deterioration, that basically results in a structural component failure. The evolution of damage will be described by the coefficient of a fractional derivative, that represents the phase field, satisfying the Ginzburg-Landau equation.
