Phenomenological Studies on Internal Friction of Noncrystalline Materials in Structural Relaxation Processes

Based on not only the ideas of phenomenological investigations about the internal friction of crystalline materials but also the studies on the internal friction laws of noncrystalline materials during structural relaxation processes in recent years,the method of making relaxation cell is put out.In the method,traditional mechanics parameter model and two-level model are unified,so phenomenological studies on the internal friction of noncrystalline materials during structural relaxation processes are made and a new relaxation law is formed.
