Fracture mechanics analysis of delamination along width-varying interfaces

The subject of controlled interface fracture is gaining considerable attention and goes hand-in-hand with ‘smart’ and ‘on-demand’ material designs and ‘metamaterial’ approach. To further unlock the potential behind geometrical enhancements, an effective crack tip forces approach is used to derive the strain energy release rate and the critical fracture onset force for layered and laminated materials of arbitrary shapes. The analytical...
