FUNDAMENTAL RHEOLOGICAL MODELING TECHNIQUE AND FRACTURE MECHANICS PRINCIPLES OF DIAMOND-CONTAINING NANOCOMPOSITES

摘要

The principal goal of the paper is to examine fracture mechanics and rheological behavior of multi-layered nanostructured materials and composites using a rheological modeling. The core principal of Newton's fundamentals was combined with rheological modeling for describing correlation between stress and deformation of nanostructured materials. Alumina-based and diamonds - containing composites (diamonds nanoparticles - aluminum, diamonds nanoparticles - polymer matrix) were studied by indentation at micro- and nano-scales. Rheological modeling as a method for determining the fracture of nanocomposites is described. Analysis of the models and experimental results revealed better understanding of nanocomposites failure and degradation mechanics. Only a deformation or a fracture load should be measured for this modeling. By measuring this minimum load, an accurate estimate of fracture may easily be calculated by applying this rheological modeling.
