DESCRIPTION:Fluid-driven delamination or fracturing occurs in a host of ma
 terials with applications to the damage of biological tissues\, the deform
 ation of engineered materials and the fracture and deformation of the Eart
 h’s crust.  This talk will focus on the dynamic spreading of viscous flu
 ids beneath purely elastic and magnetic elastic membranes.  Experimental a
 nd theoretical studies of the spreading show that bending and in-plane ten
 sion within the sheet play particularly crucial roles near the delaminatin
 g tip\, thereby determining the evolution of a fluid blister beneath thin 
 elastic sheets.  The addition of magnetic attraction provides a repeatable
  laboratory analogue in which to study the dynamics of fluid-driven fractu
 ring.  The similarities with the spreading of capillary droplets will be h
 ighlighted to highlight the conceptual links between this and previous wor
 k.
