“…Unfortunately, a typical drawback of fiber lasers is that along the cut ripples are generated, see [26,28,33]. The modeling of these ripples often relies on the introduction of imperfections in the metal or of inaccuracies in the laser management, see also [25,27]. Here, using realistic numeric parameters and in spite of the rather simplified physics involved, in Section 3 we present a first preliminary model capable of describing the formation of a geometry similar to the ripples observed in industrial cuts.…”

“…A wind, suitably provoked around the beam, pushes the melted material downwards. For its industrial interest, this phenomenon is widely considered in the specialized literature, see [13][14][15][16][26][27][28]32,33], while information specific to the cut of aluminum are for instance in [30]. A phenomenological description of the whole process can be summarized as follows.…”

For a class of systems of nonlinear and nonlocal balance laws in several space dimensions, we prove the local in time existence of solutions and their continuous dependence on the initial datum. The choice of this class is motivated by a new model devoted to the description of a metal plate being cut by a laser beam. Using realistic parameters, solutions to this model obtained through numerical integrations meet qualitative properties of real cuts. Moreover, the class of equations considered comprises a model describing the dynamics of solid particles along a conveyor belt.
