Description
Summary:'Stick-slip' deformation in g-irradiated PolyMethylMethAcrylate (PMMA) samples has been tested by means laser Dopler interferometry. Stick-slip deformation becomes apparent both at elastic and plastic PMMA flow stages. It was observed that the transition component of the creep rate can be described in the framework of Flickering noise process. The parameters of the Flickering noise process have been determined. It was concluded that Flickering noise spectroscopy can be concerned as a useful and a powerful approach, explaining the nature of stick-flip deformation in solids.
