Journal Club Theme of October 2009: Peridynamics applied to the structure and evolution of discontinuities
Discontinuities have a fundamental role in the mechanics of solids. The most famous type of discontinuity is a crack, but others are important too, such as dislocations and phase boundaries. Many types of deformation that appear to be continuous at the macroscale, such as plastic flow in metals, really involve the evolution of discontinuities at some smaller scale.
