The present study analyzes interface delamination behavior in the thermal barrier coating (TBC)/substrate system during a barb pullout test when the delamination crack is short. With the use of finite element analysis, strain energy release rates and phase angles of the delamination crack are obtain

Accurate characterization of interfacial adhesion is essential for the development of reliable wafer bonding processes. In most applications in which wafers are bonded, the interface experiences a combination of shear and normal loading (i.e., mixed-mode loading). When characterizing the fracture pr
