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

This seminar series is the continuation of the Numerical Analysis Seminar series that ran until August 2016. This change of name reflects the broader interests of the Applied Mathematics group (note that the Mathematical and Theoretical Particle Physics group also has a seminar series).
