摘要：

Starting from a one-dimensional model, we investigate the influence of viscoelasticity on the fragmentation of a surface layer, wich covers a bulk substrate. The layer is modelled as a chain of breakable springs, which is coupled to the substrate via Kelvin-Voigt elements. Letting the substrate expand, we study the dependence of the fracture patterns on the strain rate. For high strain rates the initial stage of fragmentation process is characterized by the breakage of spring which are close to each other.
