Failure and Fracture of Heterogeneous and Multilayer Materials

Often presenting better mechanical and/or multifunctional properties than their homogeneous counterparts, heterogeneous and multilayer material systems are used in a multitude of engineering applications ranging from microelectronic components to polymer composites and energetic materials. Their heterogeneous nature however complicates the analysis of their failure properties, as it has long been recognized that the macroscopic failure and fracture response in this class of materials is often dictated by complex failure processes taking place at microstructural length scales. Characterizing this link between multiple length scales continues to be a major challenge both experimentally and numerically. The objective of this symposium is to bring together experimentalists and computational scientists working on various aspects of failure of heterogeneous and multilayered materials.
