Toward a Phenomenological Model of Laser-Driven Patterning of Solid Deformable Substances

Abstract

In this report we suggest an approach to the laser-driven patterning of solids, based on the concepts of Stress-Driven Rearrangement Instabilities and the Phenomenological Mechanochemistry of Damage. We deliberately ignore all the thermal effects in order to make the role of stresses more transparent. If the suggested approach demonstrates its vitality, it should be combined with more traditional approaches. The suggested approach appears to be technically meaningful even in the absence of deformations and stresses. In this approximation, the formulated 1-D boundary value problem allows the exact solution.
