Criterion for Controlling the Stress-Strain State of Composite Dielectric Materials Using the Effective Filtration Method Vladimir Surzhikova and Pavel Fedotovb* National Research Tomsk Polytechnic University, 30, Lenina Ave., 634050, Tomsk, Russia aiva1954@mail.ru, b*pif@tpu.ru Keywords: mechanoelectric transformations, stress-strain state, dielectric, criterion.
The paper presents a brief description of a process of an electromagnetic response generation from dielectric composite materials when they are subjected to an acoustic impulses, a recording method by capacitive receivers and criteria for controlling the stress-strain state (SSS) for this method.
Introduction In the early 1970s, the Tomsk Polytechnic University researchers began to develop a new method for nondestructive testing of structural defects in dielectric materials.
Conclusions The effective filtering method with the consistency of the impulse response of the system with an excitation response of the MET acoustic pulse makes it possible to determine the level of the stress-strain state of dielectric composite materials.
