DYNAMIC CALIBRATING THEORY OF WAVES IN ELASTIC-PLASTIC MEDIA

Abstract

The dynamics of elastic-plastic media with structure has been studied. The aim is to formulate, substantiate and investigate the model permitting to describe the dynamics of interacting defect ensembles in the structural-heterogeneous materials, to investigate the different nature configuration waves on its base. The dynamic calibrating model of elastic-plastic medium has been formulated and substantiated. The normal vibration range of elastic-plastic medium and its connection with the Kosser's continuum have been found. A possibility to propagate the waves of plastic rotations and also the effects of plastic skin-layer and frequency limit have been predicted. The investigation of plastic rotation waves permits to approach to the analysis of rotating plastic motions and material damage mechanisms. The effects of frequency limit give a theoretical base for generalization of the data about plastic deformation localization in the surface layers of materialsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
