Crack Problems

3:45 PM-5:45 PM
Room 246

Problems involving the interaction of waves with cracks are technologically important, especially in the field of nondestructive evaluation. Such problems are also mathematically challenging. An idealized crack is a scatterer of zero volume: it can be modeled as a smooth open surface across which the elastic displacement vector is discontinuous. Moreover, the stresses in the surrounding solid are singular at the edge of the crack. The speakers in this minisymposium will describe recent work on a variety of crack problems with emphasis on the use of appropriate integral equations.
