Monitoring the processes of deformation and failure of solid polymeric materials from the parameters of acoustic emission signals

摘要

The importance of research into the mechanics of failure of polymeric materials goes far beyond the question of the load-bearing capacity of articles,constructions,and structures.Control of the process of failure and knowledge of its mechanisms is of huge importance for engineering and technology in different sectors of industry.For example,for constructions and structures it is desirable to improve their durability by slowing down crack growth,whereas in the machining of materials,conversely,it is expedient to reduce the strength of the material being machined for its more effective failure.
