Abstract
The problem of fracture in quasi-brittle materials is strongly linked with a zone of micro-cracking known as the fracture process zone (FPZ). For monotonic loading, the material length scale parameter D0 is used in strength scaling law to describe the transition from strength criteria to linear elastic fracture mechanics criteria.
