Abstract
The chapter presents a research dealing with the problem of the modeling of structural embrittlement in perforated metallic plates, coming from the riveting process used in aeronautics to assemble structures. The embrittlement is described as a function of two independent variables, the first variable being a geometrical one, and the second a material one. Eventually, it is shown in the chapter that the material variable of the model could be simplified in first approximation. Moreover, the embrittlement function proves to compare—in a phenomenological way—with a ramp function at each point of the crack path, the transition point being the limit between the elastic and the plastic material domains.
