• Multiscale Analysis Method for Quasi-brittle Heterogeneous Materials involving Micro-crack Propagations

抄録

It is well-known that the overall behavior of quasi-brittle inhomogeneous solids, such as rock and concrete, is governed by not only the micro-scale heterogeneities but also the change of their characteristics due to the micro-scale failure. We present a new analysis method that enables us to characterize such micro-macro coupled behavior by directly associating the crack propagations in the microstructures with the macroscopic material behavior within the framework of multi-scale modeling. Several numerical examples are presented to assess the fundamental performance of the proposed method, and to demonstrate its potential of evaluating the behavior of quasi-brittle solids in conjunction with some experimental data for validation.
