Title: Coupling gradient phenomena: Phase-Field Gradient Theory and Gradient Hyperelasticity

RSVP: Please register via Eventbrite at this link by COB Monday 20 March 2017 at



Computation is an increasingly important activity in most disciplines, leading to new fields such as computational science and engineering, computational humanities, computational finance and many others.

In this seminar Dr Espath will:

  • Present the microbalance, including the microforces, the first- and second-order microstresses for phase-field equations concomitantly with their constitutive equations, which are consistent with the free-energy imbalance
  • Provide an explicit form for the microstress structure for a free-energy functional endowed with second-order spatial derivatives; and then
  • Couple this theory with gradient elasticity through the free-energy, describing and formalizing their thermodynamics.



Dr Espath received his doctorate engineering degree at the Federal University of Rio Grande do Sul, Brazil, for work on shape optimization of shell structures and aerodynamics of compressible flows from a numerical viewpoint. Currently a postdoctoral fellow at KAUST – Stochastic Numerics group, working on Optimal Bayesian Design; his chief interests are phase field gradient theories and how they couple and interact with solids and fluids.
