Helical Buckling Behaviors of the Nanowire/Substrate System
When a nanowire is deposited on a compliant soft substrate or embedded in matrix, it may buckle into a helical coil form when the system is compressed. Using theoretical and finite element method (FEM) analyse...

Peridynamic Functionally Graded and Porous Materials: Modeling Fracture and Damage
In this chapter, we present two peridynamic models for composite materials: a locally homogenized model (FH-PD model, based on results reported in Cheng et al. (Compos Struct 133: 529–546, 2015)) and an interm...

Spherical Indentation on a Prestressed Elastic Coating/Substrate System
While there have been many studies on the indentation test of thin film/substrate systems, the primary goal has been determining the film properties. However, there was very little effort to probe the properti...
