Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
, 2007 We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Analysis of damaging process and crack propagation [PDF]
EPJ Web of Conferences, 2010 Supervising and health monitoring of structures can assess the actual state of existing structures after initial loading or in the state of operation. Structural life management requires the integration of design and analysis, materials behavior and structural testing, as given for several examples.
