Essay

This thesis is devoted to the development of new method of mode of deformation control in polymer composites, which is based on criterion of fraction power filter optimization and allows achieving minimum values of resultant errors during specimen surface displacement measurement. Optical-digital correlation device was created on the basis of the developed technique as a part of setup for control of surface deformation under static loading. The device allows us to build displacement and deformation fields near stress concentrator with high accuracy. For the first time device for speckle-images digital correlation was created for control of internal strains of diffusely scattering specimens and for definition of elastic constants under static loading.
