Identification of macroscopic material properties of multi-composed materials from finer scales of observation

摘要

In this paper, recent research projects conducted at the Institute for Strength of Materials (TU Wien), dealing with the application of the multiscale concept to different areas of civil engineering, are presented. By introducing additional observation scales below the macroscale, macroscopic material properties can be related to properties of material phases and their assemblage at finer scales of observation. The benefits arising from the use of the multiscale concept in computational mechanics and its possible impact to engineering practice are discussed by four example problems, ranging from artificial soil freezing, to the analysis of a cooling tower and a shotcrete tunnel lining, and finally to the simulation of low-temperature creep of bituminous mixtures.
